The NB4N121K and NB4N111K are 3.3V clock distribution devices with differential HCSL outputs targeted for typical FBDIMM frequencies of 100 MHz, 133 MHz, 166 MHz, 200 MHz, 266 MHz, 333 MHz and 400 MHz
Renesas added a microcontroller (MCU) to its32-bit SuperH family: the SH72546RFCC, said to be the industry's first MCU with on-chip flash memory built with a 90-nm (nanometer) process node. The device is optimized for the development of control programs for automobile engines, transmissions, and other systems that require real-time control capabilities. It achieves an operating speed of 200 MHz in the high-temperature environment (up to 125°C) required for automotive applications.
Vishay Intertechnology announced what are said to be the industry’s first power MOSFETs with on-resistance ratings at a 1.2V gate-to-source voltage in portable electronic systems. The devices bring the MOSFET turn-on voltage into alignment with the 1.2V to 1.3V operating voltages of digital ICs used in mobile electronics, enabling safer and more reliable designs. The TrenchFETs eliminate the need for an extra conversion stage in battery-operated systems with a core voltage lower than 1.8V.
Toshiba America Electronic Components introduced a second-generation, high-performance 3D comb filter front-end processor targeted at advanced analog and digital televisions, audio/video systems, set-top boxes and other video-processing systems. The TC90103AFG integrates a 3D comb filter for NTSC, a multi-standard three-line comb filter, 3D noise-reduction functions, a digital multi-standard decoder and 5 Mb of embedded DRAM for frame-buffer memory in a compact 144-pin LQFP package.
Linear Technology announced the LT1965, a low noise, low voltage 1.1A LDO with high power density. It features low dropout voltage of 300 mV at full load, with wide VIN capability of 1.8V to 20V and low adjustable output from 1.2V to 19.5V. Ultra-low output noise of only 40 µVRMS reduces noise in instrumentation, RF, DSP and logic supply systems and is beneficial for post-regulating switching power supplies.
OKW introduced a new belt/wall clip accessory for its SOFT-CASE Series which allows the enclosures to be worn on a belt and then stored on a wall, or in a cabinet, after use. With this new accessory part, the enclosures can be used for mobile electronics that are worn by a series of users and then returned to a store area after a given period, for example data logging, inventory management, medical and wellness devices and guided tour systems.
Productive Product: Fairchild Semiconductor’s 600V/30A IGBT, the FGH30N60LSD, addresses the need for low conduction losses in low-frequency (50 Hz to 400 Hz) industrial applications such as solar inverters, welding machines and uninterruptible power supplies (UPS). Featuring extremely low saturation voltage
Anritsu Company introduces three options for its MT8820B/MT8815B radio communication analyzers that allow for fast and efficient testing of TD-SCDMA 3G mobile terminals. The MT8820B-007/MT8815B-007 TD-SCDMA measurement hardware, MX882007C TD-SCDMA measurement software and the MX882007C-001 TD-SCDMA voice codec options complement the inherent testing advantages of the analyzers to provide manufacturers with an efficient test tool for conducting call-processing, RF Rx/Tx and voice tests of TD-SCDMA mobile terminals.
FETtest announces its AMX400, a modular, high-performance system for production analog/mixed-signal test applications. It offers a variety of instrumentation options, software for enterprise-wide test environments and support for avariety of devices. From wafer sort to final test, the system supports parallel testing of up to 32 multi-sites with 96 pin analog/digital stimulus/measure, software for test development and production test management and execution.
Novatech Instruments, Inc. introduces its Model 2960AX disciplined quartz frequency standard. This bench-top instrument provides a way to generate precise frequency reference signals for laboratory equipment and communication systems. Containing an ovenized quartz crystal time-base, it has a stability of better than ±5 × 10-11 per day when disciplined to a 1 pps source.
Anritsu Company introduces its MU181000B 12.5 GHz four-port synthesizer, the MU181000A/B-001 jitter modulation option and the MX180005A jitter application software for its MP1800A signal quality analyzer series. These options allow the series to conduct accurate jitter tolerance measurements on devices with up to four channels such as multi-channel CPU boards, PC boards and optical devices, forming interconnects in routers, servers and super computers.
Maxim introduced its DS1081L/DS1083L 16 MHz to 134 MHz, center spread-spectrum clock modulators. These modulators use an integrated phase-locked loop (PLL) to dither the clock output around its center frequency at a user-selectable magnitude from 0 (disabled) to ±2.0 percent, thus reducing peak EMI at fundamental and harmonic frequencies. This EMI reduction is accomplished without changing clock rise/fall times or adding the space, weight, design time

With a high safe operating area, (SOA) and low thermal resistance derived from a new thinner-die technology, the STD Series achieves high power performance in a common small package, the TO-3P. This series of parts is targeted at the home and professional audio amplifier markets.
Melexis introduced a four-channel LIN transceiver IC. It combines four LIN transceivers on one die and enables the development of simpler and more cost effective multi-LIN network master modules. Integrated 1K LIN master termination resistors and decoupling diodes further reduce system costs. This four-channel LIN transceiver is produced in 0.8µ HV-CMOS technology and is based on the single channel transceiver TH8082.
