Device Overview

Summary

The SY89231U is a precision, low jitter 3.2GHz ÷3, ÷5 clock divider with a LVDS output. The differential input includes Micrel's unique, 3-pin internal termination architecture that allows the input to interface 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 outputs are 325mV, 100K-compatible LVDS with fast rise/fall times guaranteed to be less than 200ps.The SY89231U operates from a 2.5V ±5% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. The SY89231U is part of Micrel's high-speed, Precision Edge® product line.
