Product Description
The FK Series 2.5V crystal clock oscillator
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 3.2 x 2.5mm
surface-mount ceramic package.
