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 surface-

mount ceramic package.
