Device Overview

Summary

The SY89540U is a low-jitter, low skew, high-speed 4x4 crosspoint switch optimized for precision telecom and enterprise server/storage distribution applications. The SY89540U guarantees data-rates up to 3.2Gbps over temperature and voltage.The SY89540U differential input includes Micrel's unique, 3-pin input termination architecture that directly interfaces to any differential signal (AC- or DC-coupled) as small as 100mV (200mVpp) without any level shifting or termination resistor networks in the signal path. The LVDS compatible outputs maintain extremely fast rise/fall times guaranteed to be less than 120ps.The SY89540U features a patent-pending isolation design that significantly improves on channel-tochannel crosstalk performance.The SY89540U operates from a 2.5V ±5% supply and is guaranteed over the full industrial temperature range (-40°C to +85°C). The SY89540U is part of Micrel's high-speed, Precision Edge® product line.
