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).

Three single-ended select inputs, SEL0, SEL1, and SEL2,

control the mux function. The mux select inputs are com-

patible with ECL/PECL logic, and are internally refer-

enced to the on-chip reference output (V

a low default condition if the select inputs are left open.

The differential inputs D_, D_ can be configured to

accept a single-ended signal when the unused comple-

mentary input is connected to the on-chip reference

output (V

internal bias and clamping circuits that ensure a low

output state when the inputs are left open.

The MAX9389 operates with a wide supply range V

TQFP and thin QFN packages, and operates over the

-40°C to +85°C extended temperature range.
