Product Description
The UX7040GE01 is a crystal oscillator
that achieves superb low jitter for 40GbE
applications. The output clock signal,
generated internally with a patented
oscillator design, is compatible with LVPECL
logic levels. The device, available on tape
and reel, is contained in a 7.0 x 5.0mm
surface-mount ceramic package.
