Differential Positive ECL (DPECL)

SN-A2970 Series

PRELIMINARY

Description

The SN-A2970 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.
