Differential Positive ECL (DPECL)
SK-B29B0 Series

Description
The SK-B29B0 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.
Features
