Product Description
The WF902 Series crystal oscillator achieves
superb stability over a broad range of
operating conditions and frequencies. The
low jitter output clock signal is compatible
with PECL logic levels with very good jitter
performance. The device, available on tape
and reel, is contained in a 14 x 9mm surface-
mount package.
