CRYSTAL CLOCK OSCILLATORS
Differential Positive ECL (DPECL)
Fast Edge
Data Sheet 0105C
Rev. F
SD-A2920 Series
Description
The
SD-A2920 Series
of quartz crystal oscillators provide DPECL Fast Edge compatible signals. Systems
designers may now specify space-saving, cost-effective packaged PECL oscillators to meet their timing
requirements.
