General Description
The MAX9424–MAX9427 high-speed, low-skew quad
PECL-to-ECL translators are designed for high-speed
data and clock driver applications. These devices feature
an ultra-low 0.24ps
(RMS)
random jitter and channel-to-
channel skew is less than 90ps in asynchronous mode.
The four channels can be operated synchronously with
an external clock, or in asynchronous mode determined
by the state of the SEL input. An enable input provides
the ability to force all the outputs to a differential low state.
The parts differ from one another by their input and out-
put termination options. The input options are an open
input or an internal differential 100
termination. The
output options are an open-emitter output or a series
50
termination. See
Ordering Information
.
The MAX9424–MAX9427 operate from a positive voltage
supply of +2.375V to +5.5V, and a negative supply volt-
age of -2.375V to -5.5V and operate across the extended
temperature range of -40°C to +85°C. They are offered in
32-pin 5mm x 5mm TQFP and space-saving 5mm x 5mm
QFN packages.
