ECL/PECL Dual Differential 2:1 Multiplexer
General Description
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
outputs V_BB0 and V_BB1, nominally V_CC - 1.33V.
The differential inputs D, D can be configured to accept
a single-ended signal when the unused complementary
input is connected to the on-chip supply output V_BB as
a reference voltage. All the differential inputs have bias
and clamp circuits that force the outputs to a low
default when the inputs are left open or at V_EE. The sin-
gle-ended mux select inputs have pulldowns to V_EE,
providing low default inputs when the select inputs are
left open.
The device operates with a wide supply range (V_CC -
V_EE) of +3.0V to +5.5V for PECL or -3.0V to -5.5V for
ECL, and is pin compatible with the MC100LVEL56 and
MC100EL56. The MAX9384 is offered in a 20-pin wide
SO package, and is specified for operation from -40°C
to +85°C.
