LVTTL/TTL-to-Differential LVPECL/PECL
Translators
General Description
The MAX9370/MAX9371/MAX9372 LVTTL/TTL-to-differ-
ential LVPECL/PECL translators are designed for high-
speed communication signal and clock driver
applications. The MAX9370/MAX9372 are dual
LVTTL/TTL-to-LVPECL/PECL translators that operate in
excess of 1GHz. The MAX9371 is a single translator.
The MAX9370/MAX9371 operate over a wide 3.0V to
5.25V supply range, allowing high-performance clock
or data distribution in systems with a nominal 3.3V or
5.0V supply. The MAX9372 is designed to operate from
3.0V to 3.6V.
The devices default to output high if the input is discon-
nected. They feature low 270ps propagation delay. The
MAX9370/MAX9371/MAX9372 employ industry-stan-
dard flow-through pinouts. These devices are specified
for operation from -40°C to +85°C, and are offered in
space-saving, 8-pin SOT23, µMAX, and SO packages.

Detailed Description
The MAX9370/MAX9371/MAX9372 LVTTL/TTL-to-differ-
ential LVPECL/PECL translators are designed for high-
speed communication signal and clock driver
applications. The MAX9370/MAX9372 are dual LVTTL-
to-LVPECL/PECL translators that operate in excess of
1GHz. The MAX9371 is a single translator. The
MAX9370/MAX9371 operate over a wide 3.0V to 5.25V
supply range, allowing high-performance clock or data
distribution in systems with a nominal 3.3V or 5.0V sup-
ply. The MAX9372 is optimized for 3.0V to 3.6V opera-
tion. These devices feature low 270ps propagation
delay and 40ps peak-to-peak deterministic jitter.
Inputs and Outputs
The MAX9370/MAX9371/MAX9372 inputs accept stan-
dard LVTTL/TTL levels. The input has pullup circuitry that
drives the outputs to a differential high if the inputs are
open. The outputs are differential LVPECL/PECL levels.
Applications Information
Output Termination
Terminate outputs with 50Ω to VCC - 2V or use an equiv-
alent Thevenin termination. Use the same terminate on
each output for the lowest output-to-output skew. When a
single-ended signal is taken from a differential output,
terminate both outputs. For example, if Q is used as a
single-ended output, terminate both Q and Q.
