Product Description
The SEL383 Series is a 3.3V crystal clock oscillator that
achieves superb jitter and stability over a broad range of
operating conditions and frequencies. 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 7x5mm
surface-mount ceramic package.
