LVTTL/TTL-to-Differential LVPECL/PECL
Translators
General Description
Features
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.
ꢀ Guaranteed 1GHz Operating Frequency at 600mV
Differential Output
ꢀ 270ps Propagation Delay
ꢀ 10ps Output-to-Output Skew (MAX9370/MAX9372)
ꢀ Wide Supply Range: 3.0V to 5.25V
(MAX9370/MAX9371)
ꢀ ESD Protection > 2kV (Human Body Model)
ꢀ Output High with Input Open
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.
ꢀ Available in Small 8-Pin SOT23, µMAX, and SO

Inputs and Outputs
Detailed Description
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.
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.
Applications Information
Output Termination
Terminate outputs with 50Ω to V
- 2V or use an equiv-
CC
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.

LVTTL/TTL-to-Differential LVPECL/PECL
Translators
Ensure that the output currents do not exceed the con-
tinuous safe output current limit or surge output current
limit as specified in the Absolute Maximum Ratings
table. Under all operating conditions, the device’s total
thermal limits should be observed.
PC Board Traces
Input and output trace characteristics affect the perfor-
mance of the MAX9370/MAX9371/MAX9372. Connect
each differential output to a 50Ω characteristic impedance
trace. Minimize the number of vias to prevent impedance
discontinuities. Reduce reflections by maintaining the 50Ω
characteristic impedance through connectors and across
cables. Reduce skew within a differential pair by match-
ing the electrical length of the traces.

ceramic 0.1µF and 0.01µF capacitors in parallel and as
close to the device as possible, with the 0.01µF capaci-
tor closest to the device. Use multiple parallel vias to
minimize parasitic inductance.
