Microchip SY89112UMY

扇出缓冲器（分配），多路复用器12：12

Overview

The SY89112UMY is a low-jitter, low-skew, high-speed LVPECL 1:12 differential fanout buffer optimized for precision telecom and enterprise server distribution applications. The input includes a 2:1 MUX for clock switchover application. Unlike other multiplexers, this input includes a unique isolation design to minimize channel-to-channel crosstalk. The SY89112UMY distributes clock frequencies from DC to >2GHz guaranteed over temperature and voltage. The SY89112UMY incorporates a synchronous output enable (EN) so that the outputs will only be enabled/disabled when they are already in the LOW state. This reduces the chance of generating "runt" clock pulses.The SY89112UMY differential input includes Micrel's unique, patent-pending 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. For AC-coupled input interface, an on-board output reference voltage (VREF-AC) is provided to bias the center-tap (VT) pin. The outputs are 800mV, 100K-compatible LVPECL with fast rise/fall times guaranteed to be less than 220ps.The SY89112UMY operates from a 2.5V ±5% or 3.3V ±10% supply and is guaranteed over the full industrial temperature range of -40°C to +85°C. The SY89112UMY is part of Micrel's high-speed, Precision Edge® product line.
