10/4/2002 - TDK Semiconductor's 78Q2120 Fast Ethernet PHY, one of the computer industry's best known Ethernet transceivers, has been qualified by NVIDIA Corporation for use with NVIDIA's new nForce2TM family of platform processors, a revolutionary graphics and multimedia PC architecture.
TDK Semiconductor's expertise is in mixed-signal technologies and products, such as digital/analog interfaces and line drivers. Its 78Q2120 functions at the physical layer interface to make the digital/analog connection to standard Ethernet and Fast Ethernet media. A product like this is necessary for every device using Ethernet, including desktop and computers, game consoles, and set-top boxes.
"We believe TDK has set the quality benchmark for Ethernet transceivers," said Brian Truesdale, the company's vice president of marketing and business development. "Our return rate from customers is 100 DPPM (defective parts per million). Thatís one-tenth the failure rate of competitive PHYs. To our knowledge, not one faulty 78Q2120 has ever found its way into a end-user customer's hands."
"We are impressed with TDK's quality rating, and that's why we asked TDK to submit its part for our qualification testing," said Drew Henry, senior director of platform business at NVIDIA. "TDK's fast Ethernet PHY came through with flying colors, and we are convinced that graphics and multimedia applications taking advantage of our nForce2 platform processors and TDK's 78Q2120 transceiver will experience the best of both worlds-performance and reliability."
About the 78Q2120
TDK Semiconductor made its mark in the Fast Ethernet market with the 78Q2120 when it was offered as the world's first 3.3V and 5V 10/100TX PHY. TDK's successful inroads to mobile computing applications occurred in part because the 78Q2120 offered the lowest power consumption available (313mW, maximum). In addition to mobile use, the device proved well suited for applications confined by stringent power requirements, long cable lengths and non-CAT-5 line segments.
The TDK 78Q2120 includes an integrated Media Independent Interface, ENDECs, scrambler/descrambler, dual-speed clock recovery, and auto-negotiation functions. The transmitter includes an on-chip pulse-shaper and a low-power line driver. The receiver has an adaptive equalizer and a baseline restoration circuit required for accurate clock and data recovery. The transceiver interfaces to Cat-5 or Cat-3 unshielded twisted pair (UTP) cabling, and is connected to the line media via 1:1 isolation transformers. No external filter is required.
