General Description
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
BB1
, V
BB2
),
nominally V
CC
- 1.425V. The select inputs accept signals
between V
CC
and V
EE
. Internal pulldowns to V
EE
ensure
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
BB1
, V
BB2
). All the differential inputs have
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
CC
-
V
EE
of 2.375V to 5.5V. The device is offered in 32-pin
TQFP and thin QFN packages, and operates over the
-40°C to +85°C extended temperature range.
