DESCRIPTION
The ABX0027B form a low cost family of XO IC’s,
designed to consume the lowest current on the mar-
ket for the 10MHz to 52MHz range. It accepts fun-
damental resonant mode crystal input from 10 to
52MHz. Providing less than -145 dBc at 10kHz offset
at 30MHz and with a very low jitter (2.5 ps RMS pe-
riod jitter) makes this chip ideal for applications re-
quiring low current frequency sources.
