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 VBB 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.
Features
o Guaranteed 2.0GHz Operating Frequency
o 250ps (typ) Propagation Delay
o 1.0ps RMS Jitter (typ)
o 2.375V to 2.625V Low-Voltage Supply Range

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
DC ELECTRICAL CHARACTERISTICS
(VCC = 2.375V to 2.625V for MAX9374, VCC = 3.0V to 3.6V for MAX9374A, 100±1% across outputs, VID = 0.095V to VCC or 3V,
whichever is less, VIHD = 1.2V to VCC, VILD = GND to VCC - 0.095V, unless otherwise noted. Typical values are at VIHD = 2.0V, VILD =
1.85V, VCC = 3.3V for MAX9374A, VCC = 2.5V for MAX9374.) (Notes 1, 2)
