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

Footnotes:
1) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization.
RMS jitter bandwidth of 12kHz to 20MHz.
2) Frequency increase with increase in control voltage and is monotonic.
