GENERAL DESCRIPTION
The FASTPULSE high speed LAN transceivers provide high performance, cost-effective solutions for ATM 155 Mbps, TPFDDI and Fast Ethernet 100Base-TX frontends. The transceivers interface the standard “fiber” PECL interface to UTP-5 cable, integrating the transceiver IC, magnetics and connector in the process. The highly compact design implements the entire Physical Media Dependent (PMD) circuit in the standard 9-pin form factor, which reduces component count and board space. This modular transceiver approach, minimizes the design effort and risk of implementing 100 Mbps + frontends. Employing FASTPULSE technology, these transceivers integrate the full transmit/receive interface functions of signal encoding/ decoding, adaptive equalization, DC restoration, signal filtering, and isolation. This integrated approach, coupled to the novel circuit design, results in a high performance frontend which eliminates many of the conventional design compromises and parasitic elements which plague high speed designs.
