CRYSTAL CLOCK OSCILLATORS
Differential Positive ECL (DPECL)
Data Sheet 0325B
Rev. B
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.
