SK-A2910
Series
Differential Positive ECL (DPECL)
SK-A2910 Series
Rev H
Frequency Range: 100.0 MHz to 320.0 MHz
Description
The SK-A2910 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.
