Product Description

Common Frequencies

Contact SaRonix for additional frequencies

The SEL381 Series is a 3.3V crystal clock oscillator

that achieves superb stability over a broad range of

operating conditions and frequencies. The output

clock signal is compatible with LVPECL logic levels.

The device, available on tape and reel, is contained in

a 5x7mm surface-mount ceramic package.
