Catalyst Semiconductor announced two additions to its low dropout (LDO) regulator product line. The CAT6217 and CAT6218 LDO regulators source 150 mA and 300 mA output currents, respectively, in a five-lead, 1 mm profile thin SOT-23 package. The regulators offer a low quiescent current combined with a low typical dropout voltage of 90mV at a 150 mA load for the CAT6217 and 180 mV at a 300 mA load for the CAT6218.
Wolfson Microelectronics launched the WM8941, a high-performance low-power CODEC with an integrated video buffer and speaker driver for use in digital still and video cameras. The mono CODEC uses four programmable notch filters to provide quality audio recording, while the integrated video buffer provides direct connectivity to a television. The company integrated the CODEC, video buffer and speaker driver in a 4 mm ×4 mm chip.
Vativ Technologies announced the sample availability of its VTV2313 supporting the new features introduced in the HDMI 1.3a specification. In addition to being pin-compatible with the company’s first-generation three-input HDMI receiver (VTV2310), the VTV2313 supports xvYCC and up to 36-bit Deep Color at 1,080p and UXGA resolutions. Maximum bandwidth supported by the receiver is 6.75 Gbps at 225 MHz.
Valpey Fisher Corporation introduced the VFJA432 and VFJA434 integrated timing modules for synchronizing Ethernet. The timing modules can synchronize an Ethernet physical layer to a telecom network timing reference while generating a 0.18 picosecond jitter Ethernet clock. The modules can synchronize to common telecom frequencies such as 8 KHz and 19.44 MHz from the backplane or common Ethernet frequencies such as 25MHz and 125 Mhz from the physical layer
Maxim Integrated Products introduced its MAX4886 quad, high-speed, high-bandwidth, HDMI/DVI passive switch capable of switching between two digital video signals into a single monitor or multiple HDMI/DVI connectors while maintaining a high level of signal integrity. To ensure signal integrity at fast switching rates, the device features a wide common-mode signal range that enables rail-to-rail signal switching at data rates in excess of 4 Gbps.
Supertex introduced the HV610, a 32-channel, serial-to-parallel converter with high voltage, push-pull outputs. The IC is suited for driving high-speed printers and LCD displays. Its outputs can be individually controlled, set to high or low, or set to a high-Z state, providing useful versatility in applications requiring fast shift register and data shifting speeds.
ALFATxp, offered by Saelig, brings FAT file system access to SD/MMC media from any USB port, but also includes a Java machine for handling additional tasks. It acts as a card reader through a built-in USB peripheral port, so files can be shared between a PC and custom-design products. The chip is also appropriate for data logging applications. It communicates with SD/MMC cards and creates files and directories on them.
Winbond Electronics Corporation America announced the production-release of two members in its SpiFlash 25X family of Serial Flash memories. Suited for makers of computer, networking and consumer applications, the W25X16 and W25X32 SpiFlash memories offer 16 Mb and 32 Mb densities in an 8-pin SOIC package.
The PPS Gen 2 is an addition to IDT’s wireless infrastructure line and the newest member of the company’s Serial RapidIO-enabled pre-processing switch (PPS) family, which addresses the interconnect and acceleration needs of 3G and beyond. The PPS Gen 2 optimally distributes data to the DSP cluster to prevent bottlenecks, and it performs end-point functions -- such as lower-level data manipulation -- freeing the DSP to support higher value-added services and differentiating algorithms.
Micrel’s SY88973BL low-power limiting post amplifier is designed for use in fiber optic receivers; specifically, it is suited for 1.25 Gbps and 2.5 Gbps Gigabit Ethernet, 1.062 Mbps and 2.125 Gbps Fibre Channel, Gigabit interface converter (GBIC), Small Form Factor (SFF) and SFP transceivers, parallel 10G Ethernet, high-gain line drivers and line receivers in both the Telecom/datacom and Optical transceiver markets.
Productive Product: What if physics research into levitation could lead to frictionless electromechanics? Levitation is cool, but think of all the power you'd save in new product designs. It may soon be possible because scientists at the University of St. Andrews figured
Microchip Technology is providing free source code for the sensorless field oriented control (FOC) of permanent magnet synchronous motors (PMSMs), which can operate on any of the company’s motor control dsPIC digital signal controllers (DSCs) -- including the DSCPIC33FJ12MC family of DSCs. The algorithm is free, and prices for the DSCPIC33FJ12MC family start at $1.99 each in 10,000-unit quantities.
Microchip Technology’s PIC24HJ12 family of 40 MIPS, 16-bit microcontrollers is offered in 18- and 28-pin packages as small as 6 mm × 6 mm for space-constrained applications. The family’s 16-bit MCU architecture was designed for engineers that need to migrate from 8-bit architectures. The company offers 92 sixteen-bit products in four compatible families to serve users for years, even as they scale to DSP-enabled applications.
Microchip Technology introduced the dsPIC33FJ12MC family of motor control digital signal controllers (DSCs). These 40 MIPS DSCs provide a platform for advanced motor control algorithms such as field-oriented control (FOC), enabling desirable performance, and low noise plus power efficiency for motor control applications. The family is available in 20- and 28-pin packages as small as 6 mm ×6 mm.
Microchip Technology announced the dsPIC33FJ12GP family of digital signal controllers (DSCs), which are suited for a new class of smart sensor applications. With 40 MIPS performance in package sizes as small as 6 mm ×6 mm, the processor can be moved closer to the sensor -- eliminating lead noise and offloading this workload from a central processor -- thereby creating a smart sensor scenario. Using libraries and filter design tools, digital filters can replace analog filters to reduce noise.
