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
Packages
ꢀ Improved Upgrades to MC100EL22, MC100EPT20,
MC100EPT22
