CRYSTAL CLOCK OSCILLATORS
Positive ECL (PECL)
Data Sheet 9727A
Rev. N
HA-A870 Series
Description
The
HA-A870 Series
of quartz crystal oscillators provide MECL 10K and 10KH series compatible signals in
industry standard four pin DIP hermetic package. Systems designers may now specify space-saving, cost-
effective packaged PECL oscillators to meet their timing requirements.
Features
