Differential LVPECL-to-LVDS Translators
General Description
The MAX9374 and MAX9374A are 2.0GHz differential
LVPECL-to-LVDS translators and are designed for tele-
com applications. They feature 250ps propagation
delay. The differential output conforms to the ANSI
TIA/EIA-644 LVDS standard. The inputs are biased with
internal resistors such that the output is differential low
when inputs are open. An on-chip V_BB reference output
is available for single-ended operation.
The MAX9374 is designed for low-voltage operation
from a 2.375V to 2.625V power supply for use in 2.5V
systems. The MAX9374A is designed for 3.0V to 3.6V
operation in systems with a nominal 3.3V supply. Both
devices are offered in industry-standard 8-pin SOT23
and SO packages.
