Product Description
The SRS383 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 contains a divide-by-2 RateSelect™ function
that toggles the output frequency and is available on
tape and reel, is contained in a 7x5mm surface-mount
ceramic package.
