CRYSTAL CLOCK OSCILLATORS
Differential Positive ECL (DPECL)
Data Sheet 9235A
Rev. N
HK-2900 Series
Description
The
HK-2900 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.
