Product Description
The S19xx Series is a 3.3V or 5V crystal clock oscillator
that achieves superb stability and fast rise/fall edges
over a broad range of operating conditions and
frequencies. The output clock signal, generated
internally with a PLL oscillator design, is compatible
with ACMOS/TTL logic levels. The device, available
on tape and reel, is contained in a 5x7mm surfacemount ceramic package.
