NEL SD-A3679-FREQ

SD-A3670
Series
VCXO Series (PECL)
SD-A3670 Series Rev H
Frequency Range: 70.0 MHz to 200.0 MHz
Description
The SD-A3670 Series of voltage controlled quartz crystal oscillators provide frequency control by applying a
voltage to Pin 1. This unit supplies DPECL compatible outputs which are enabled when Pin 2 is set to a logic
low or left open.
