CRYSTAL CLOCK OSCILLATORS
Rev. C
Differential Positive ECL (DPECL)
SK-2910 Series
Description
The SK-2910 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.
