Product Description
The KX251 Series real time clock oscillator
achieves superb stability over a broad range
of operating conditions. It utilizes Pericom
proprietary technology to achieve ultra low
current less than 10µA. The output clock
signal is compatible with LVCMOS/LVTTL logic
levels. The device, available on tape and reel,
is contained in a 2.5 x 2.0mm surface-mount
ceramic package.
