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