General Description
The MAX9325 low-skew, 2:8 differential driver features
extremely low output-to-output skew (50ps max) and
part-to-part skew (225ps max). These features make
the device ideal for clock and data distribution across a
backplane or board. The device selects one of the two
differential HSTL or LVECL/LVPECL inputs and repeats
them at eight differential outputs. Outputs are compati-
ble with LVECL and LVPECL, and can directly drive
50 terminated transmission lines.
The differential inputs can be configured to accept a
single-ended signal when the unused complementary
input is connected to the on-chip reference output volt-
age VBB. All inputs have internal pulldown resistors to
VEE. The internal pulldowns and a fail-safe circuit
ensure differential low default outputs when the inputs
are left open or at VEE.
The MAX9325 operates over a 2.375V to 3.8V supply
range for interfacing to differential HSTL and LVPECL
signals. This allows high-performance clock or data dis-
tribution in systems with a nominal +2.5V or +3.3V sup-
ply. For LVECL operation, the device operates with a
-2.375V to -3.8V supply.
The MAX9325 is offered in 28-lead PLCC and space-
saving 28-lead QFN packages. The MAX9325 is speci-
fied for operation from -40°C to +85°C.
