Differential 8:1 ECL/PECL Multiplexer with

Dual Output Buffers

General Description

Features

The MAX9389 is a fully differential, high-speed, low-jitter,

8-to-1 ECL/PECL multiplexer (mux) with dual output

buffers. The device is designed for clock and data distri-

bution applications, and features extremely low propa-

gation delay (310ps typ) and output-to-output skew

(30ps max).
