ECL/PECL Dual Differential 2:1 Multiplexer
General Description
Features
The MAX9384 fully differential dual 2:1 multiplexer
(mux) features extremely low propagation delay (560ps
max) and output-to-output skew (40ps max). The
device is ideal for clock and data multiplexing applica-
tions. The two 2:1 muxes are controlled individually or
simultaneously through mux select inputs COM_SEL,
SEL0, and SEL1. The mux select inputs are compatible
with ECL/PECL logic, and are referenced to on-chip
