Device Overview

Summary

The SY89113U is a 2.5V low jitter, low skew, 1:12 LVDS fanout buffer optimized for precision telecom and enterprise server distribution applications. The input includes a 2:1 MUX for clock switchover applications. Unlike other multiplexers, this input includes a unique isolation design that minimizes channel-to-channel crosstalk. The SY89113U distributes clock frequencies from DC to >1GHz guaranteed over temperature and voltage. The SY89113U incorporates a synchronous output enable (EN) so that the outputs will only be enabled/disabled when they are already in the LOW state.

CLK0 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.CLK1 differential input includes a new version of unique, Any-Input architecture that directly interfaces with single-ended TTL/CMOS logic (including 3.3V logic), single-ended LVPECL, differential (AC- or DC-coupled) LVDS, HSTL, CML, and LVPECL logic levels as small as 200mV (400mVPP). CLK1 input requires external termination.LVDS output swing 325mV into 100Ω with extremely fast rise/fall time guaranteed to be less than 250ps.The SY89113U operates from a 2.5V±5% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. The SY89113U is part of Micrel's high-speed, Precision Edge® product line.
