Product Description
The S1644 Series is a 2.5V crystal clock oscillator that
achieves superb stability and low power consumption
over a broad range of operating conditions and
frequencies. The low jitter output clock signal,
generated internally with a non-PLL oscillator design,
is compatible with LVCMOS logic levels. The
device, available on tape and reel, is contained in a
3.2x2.5mm surface-mount ceramic package.
