Differential Positive ECL (DPECL)

SR-A29B0

Series

SR-A29B0 Series Rev G

Frequency Range: 250.0 MHz-1.7 GHz

Description

The SR-A29B0 Series of quartz crystal oscillators provide DPECL Fast Edge compatible

signals. This device is to operate using positive voltage and uses multiple ground pins for

improved signal integrity. This device is intended to operate on positive voltage for PECL

applications.
