SY89837U - PRECISION 1:8 LVPECL FANOUT BUFFER

General Description

The SY89837U is a low jitter, low skew, high-speed 1:8 fanout buffer with a unique, 2:1 differential input multiplexer (MUX) optimized for clock redundant switchover applications.

Key Features

  • Selects between two clocks, and provides 8 precision, low skew LVPECL output copies.
  • Guaranteed AC performance over temperature and supply voltage:.
  • Wide operating frequency: 1kHz to >1.5GHz.
