DESCRIPTION
The PLL600-27/-37 form a low cost family of XO
IC’s, designed to consume the lowest current on the
market for the 10MHz to 52MHz range. It accepts
fundamental resonant mode crystal input from 10 to
52MHz. Providing less than -130dBc 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.
