Product Description
The KM Series real time clock oscillator
achieves superb stability over a broad range
of operating conditions. The output clock
signal is compatible with LVCMOS/LVTTL logic
levels. The device, available on tape and reel,
is contained in a 2.0 x 1.6mm surface-mount
ceramic package.
