Microchip | SY89846UMG

The SY89846UMG is a Part of SY89846U Series, 2.5/3.3 V, 1:5 LVPECL fanout buffer with a 2:1 differential input multiplexer (MUX). It comes in a Package of MLF-32 and its operating temperature ranges from -40 °C to 85 °C.

Features:

• Selects between two inputs, and provides 5 precision LVPECL copies
• Fail-Safe Input
• Prevents outputs from oscillating when input is invalid
• Guaranteed AC performance over temperature and supply voltage:
• DC-to >1.5GHz throughput
• < 900ps Propagation Delay ( IN-to-Q)
• < 250ps Rise/Fall times
• Ultra-low jitter design:
• <1psRMS random jitter
• <1psRMS cycle-to-cycle jitter
• <10psPP total jitter (clock)
• <0.7psRMS MUX crosstalk induced jitter
• Unique, patented MUX input isolation design minimizes adjacent channel crosstalk
• Unique patented internal termination and VT pin accepts DC- and AC-coupled inputs (CML, PECL, LVDS)
• Wide input voltage range VCC to GND

Applications:

• Fail-safe clock protection
• SONET clock distribution
• Backplane distribution
