Dual-port Gigabit Ethernet transceiver
National Semiconductor has announced the DP83862, a low-cost, highly integrated dual-port 10/100/1000 physical layer transceiver.
World's smallest multifunction supervisory ICs
National Semiconductor has announced a family of supervisory ICs with a variety of factory-programmable features that can be configured in hundreds of possible combinations.
It features low power dissipation for greater reliability and lower overall system component cost.
Paired with National's CLC030 serial digital video encoder, the CLC031A greatly simplifies the data transfer interface for HDTV equipment designers.
"The CLC031A not only offers broadcast video equipment suppliers standard- and high-definition capability on a single chip, it also provides ESD protection that is six times greater than competitor solutions", said Thomas Wirschem, Product Marketing Manager Communications Interface Division Europe.

Frugal dual-channel A/D conversion
National Semiconductor has introduced a dual-channel 8bit A/D convertor with record low-power dissipation levels.
"With the level of investment that goes into these systems and their direct connection to cables in harsh environments, the CLC031A provides much needed protection and the performance that only National's high-speed interface products can deliver".
National Semiconductor has leveraged its analogue design expertise to optimise the analogue signal-handling capability of the deserialiser.
The wide common mode input range of the CLC031A translates into a broader choice of serial interface signalling options.
Video system processing performance is improved by its increased output timing margins and reduced jitter.
Designed to support the interface requirements of professional HDTV broadcast equipment, the CLC031A accepts serial data at rates from 270Mbit/s to 1.485Gbit/s and converts it per the SMPTE standard to parallel data (10bit for standard definition video, 20bit for high definition video) with a parallel rate clock.
The standard serial interfaces used in such equipment are SMPTE 259M for standard definition video signals and SMPTE 292M for high definition video signals.
The CLC031A supports multiple standards, allowing it to become a truly universal interface circuit.
Additional functions include the ability to extract ancillary data (ANC) packets from the serial data stream via a low-speed first in, first out (FIFO) interface.
National Semiconductor has published a "Broadcast video owner's manual", which includes an introduction to broadcast video signals and standards, system design recommendations and system testing.
The manual also describes National's broadcast video products and evaluation boards, and can be downloaded from the company's website.
The CLC031A, along with a previously announced encoder and crosspoint switch, are the initial components in a new series of high-definition products from National that will provide a complete serial signal processing chain solution to video system designers.
Soon, a cable driver, cable equaliser and data retimer will complete the chipset, enabling a point-to-point interface that will support a datalink at up to 1.485Gbit/s over a distance of 140m.
In addition to the HDTV data transfer chipset, National offers a comprehensive portfolio of analogue video wideband amplifiers, video buffers and high-speed single and triple A/D convertors.
Available now and packaged in a 64-pin PQFP, the CLC031A is priced at $35.00 when purchased in quantities of 1000.
