Low-Power High-Speed 28nm CMOS Converters

2013-06-19T09:31:30-07:00

Fujitsu announced the first in a new family of 8-bit, power-efficient, 28nm CMOS converters. The analog-to-digital converter (ADC) addresses the need for large-scale global deployment of single-wavelength, 100Gbps optical transport systems, and provides a solution for future short-range optical and backplane interconnects. Now in its third generation of process technology, the 28nm ADC supports sampling rates from 55 to 70 GSa/s (billions of samples per second) with scalable analog bandwidth. The new ADC, which is based on Fujitsu’s proven CHAIS architecture, will be shown for the first time at the OFC/NFOEC conference, March 18-21, in Anaheim, California.Fujitsu Semiconductor America (FSA) today introduced an ultra-low-power Ferroelectric Random Access Memory (FRAM) in a new, smaller standard SON-8 package designed for miniaturized products.

Fujitsu will expand the new 8-bit family this year with the release of a digital-to-analog converter (DAC) with the same sampling range. Subsequent ADC and DAC devices, all of which will be available for system design in 2013, will support sampling rates ranging from 28 GSa/s to more than 90 GSa/s. The converters, which can be used in a variety of different channel-count configurations, offer significantly lower power based on sampling rate when compared to previous 40nm CHAIS converters from Fujitsu.

Ever-increasing bandwidth and traffic demands are shifting the requirement for 100Gbps lambdas from the long-haul network (where they run over a few thousand kilometers) to the mid-haul or Metropolitan Area Network (MAN). While distances are shorter in Metro networks (up to a few hundred kilometers), port densities are higher, resulting in mechanical and thermal constraints that require more power-efficient 100Gbps SoC designs.

In addition to their use in 100Gbps long-haul and metro optical transport networks, solutions based on advanced modulation techniques—combined with high-speed, high-resolution low-power converters—can address the increasing bandwidth demands of a number of other sectors. These include inter- and intra-datacenter optical links for 100Gbps Ethernet, as well as high-speed electrical interconnects across PCB or backplane channels. As in the Metro transport market, increasing bandwidth and traffic demands are pushing high-speed converter designs to be more flexible and power-efficient.

Building on years of design experience spanning multiple process generations, Fujitsu continues to be at the forefront of analog design. Fujitsu brings its expertise in mixed-signal, thermal, power-optimization and high-performance package design to ensure successful implementation of high-speed SoC ASIC designs to meet these new and growing market challenges.

A member of IDT’s Zero-Distortion family, the new device reduces distortion while simultaneously reducing power consumption in Long Term Evolution (LTE) and time-division duplexing (TDD) wireless communication architectures. The new LTE mixer is an important RF product in IDT’s strategy to provide the industry with a complete radio card signal chain, from the antenna to the digital signal processors (DSPs).

The IDTF1162 is a low-power, low-distortion dual 2300-2700 MHz RF to IF mixer with an ultra-linear (+43 dBm) third-order intercept point (IP3O) for superb intermodulation rejection, making it ideal for multi-carrier, multi-mode cellular systems found in 4G wireless base station transceivers. Compared to competitive solutions, the IDTF1162 improves IM3 distortion by 18 dB while simultaneously reducing power consumption by an industry-leading 40 percent (1150 mW typical). These attributes ease heat-sinking requirements on the radio card and allow infrastructure vendors to utilize higher average frontend gain settings, which results in higher signal-to-noise ratio (SNR).

Energy-Efficient CV/CC Switcher

2013-06-18T15:00:21-07:00

LinkSwitch-HF integrates a 700 V power MOSFET, oscillator, simple ON/OFF control scheme, a high voltage switched current source, frequency jittering, cycle-by-cycle current limit, and a thermal shutdown circuitry into a monolithic IC. The start-up and operating power are derived directly from the DRAIN pin, eliminating the need for a bias winding and associated circuitry. The 200 kHz maximum switching frequency allows very low ﬂux transformer designs, practically eliminating audible noise with the simple ON/OFF control scheme using standard varnished transformer construction. Efﬁcient operation at this high switching frequency is achieved due to the optimized switching characteristics and small capacitances of the integrated power MOSFET. The fully integrated auto-restart circuit safely limits output power during fault conditions such as output short circuit or open loop, reducing component count and secondary feedback circuitry cost. The internal oscillator frequency is jittered to signiﬁcantly reduce both the quasi-peak and average EMI, minimizing ﬁltering cost.

Description:

Energy-efficient replacement for regulated linear transformer and discrete power supply designs
Universal input range allows worldwide operation
Self-biased supply – saves transformer auxiliary winding and associated bias supply components
Built-in current limit and hysteretic thermal shutdown protection

Logic Controlled High-Side Power Switch

2013-06-18T09:30:36-07:00

The NX5P1000 is an advanced power switch and ESD- protection device for USB OTG applications. The device includes under voltage and over voltage lockout, over-current, over-temperature, reverse bias and in-rush current protection circuits. These circuits are designed to isolate a VBUS OTG voltage source automatically from a VBUS interface pin when a fault condition occurs. The device features two power switch terminals, one input (VINT) and one output (VBUS). It has a current limit input (ILIM) for defining the over-current and in-rush current limit. A voltage detect output (VDET) is used to determine when VINT is in the correct voltage range. An open-drain fault output (FAULT) indicates when a fault condition has occurred and an enable input (EN) controls the state of the switch. When EN is set LOW the device enters a low-power mode, disabling all protection circuits except the undervoltage lockout. The low-power mode can be entered at anytime unless the over temperature protection circuit has been triggered.

Designed for operation from 3 V to 5.5 V, it is used in power domain isolation applications to protect from out of range operation. The enable input includes integrated logic level translation making the device compatible with lower voltage processors and controllers.

Hex Multiplexer for PCI Express

2013-06-18T03:09:12-07:00

The CBTL06141 is a six-channel (‘hex’) multiplexer for DisplayPort and PCI Express applications at Generation 1 (‘Gen1’) speeds. It provides four differential channels capable of 1 : 2 switching or 2 : 1 multiplexing (bidirectional and AC-coupled) PCI Express or DisplayPort signals, using high-bandwidth pass-gate technology. Additionally, it provides for switching/multiplexing of the Hot Plug Detect signal as well as the AUX or DDC (Direct Display Control) signals, for a total of six channels on the display side. The AUX and DDC channels provide a four-position multiplexer such that an additional level of multiplexing can be accomplished when AUX and DDC I/Os are on separate pins of the display source device.

The CBTL06141 is designed for Gen1 speeds, at 2.5 Gbit/s for PCI Express or 2.7 Gbit/s for DisplayPort, and for input voltages of up to 3.3 V typical. It consumes very low current in operational mode (less than 1 mA typical) and provides for a shutdown function (less than 10 μA) to support battery-powered applications.

A typical application of CBTL06141 is on motherboards where one of two GPU display sources needs to be selected to connect to a display sink device or connector. A controller chip selects which path to use by setting a select signal HIGH or LOW. Due to the non-directional nature of the signal paths (which use high-bandwidth passgate technology), the CBTL06141 can also be used in the reverse topology, e.g., to connect one display source device to one of two display sink devices or connectors.

Optionally, the hex MUX device can be used in conjunction with an HDMI/DVI level shifter device (PTN3300A, PTN3300B or PTN3301) to allow for DisplayPort as well as HDMI/DVI connectivity.

Real-Time Power Monitoring and Code Optimization

2013-06-14T03:00:42-07:00

Microchip Technology Inc. announced the MPLAB® REAL ICE™ Power Monitor Module, which enables designers to identify and eliminate code that consumes high current, in real time. Combined with the MPLAB REAL ICE in-circuit emulator and MPLAB X IDE, this development platform allows users to measure, graphically profile and optimize code power consumption for all of Microchip’s more than 1000 8-bit, 16-bit and 32-bit PIC® microcontrollers. Additionally, it offers unsurpassed micro-Amp current measurement, with an overall dynamic range up to 1 Amp, and a voltage range of 1.25V to 5.5V. At a list price of $379.99, Microchip’s Power Monitor Module is significantly more cost effective than similar tools, making it ideal for a broad range of battery-powered, digital power-supply, motor-control and metering applications.

Embedded designers continue to seek new ways to optimize power consumption for both extended battery life and greater line-power efficiency. As MCU vendors and users have greatly reduced hardware power consumption—such as the 9 nA sleep and 30 µA/MHz active current consumption of Microchip’s eXtreme Low Power (XLP) PIC MCUs—application software is the next place for engineers to focus. Microchip’s Power Monitor Module provides programmable power to the target, as well as sampling intervals, enabling users to run at specific voltage levels and see tailored measurements. Designers can also set a “current break” threshold level that breaks when exceeded, allowing them to pinpoint the code causing the spike and debug it. All of these measurements can be displayed graphically, via the “Current Profile Graphing” feature, enabling engineers to better understand which sections of their code are consuming higher current.

“The MPLAB REAL ICE Power Monitor Module meets our customers’ need for a low-cost software optimization tool that enables them to squeeze every last drop of power efficiency out of their code,” said Derek Carlson, Microchip’s vice president of Development Tools. “Together with our XLP PIC microcontrollers for battery-powered applications, and our MCUs and dsPIC® digital signal controllers for digital power conversion, motor control and metering, Microchip now provides the industry’s first complete low-power embedded design platform.”
