Differential Positive ECL (DPECL)
SK-A2910 Series Rev H
SK-A2910
Series
Frequency Range: 100.0 MHz to 320.0 MHz
Description
The SK-A2910 Series of quartz crystal oscillators provide DPECL Fast Edge coꢀpatible signals. This device
is to operate using positive voltage and uses ꢀultiple ground pins for iꢀproved signal integrity. This device is
intended to operate on positive voltage for PECL applications.
