DESCRIPTION

The PLL600-17/-27/-37 form a low cost family of XO
IC's, designed to consume the lowest current on the
market for the 5MHz to 52MHz range. It accepts
input crystal from 10 to 52MHz (fundamental
resonant mode) and offers a selectable divider by 2
(PLL600-17 only) or no division. Providing less than
-130dBc at 10kHz offset at 30MHz, and with a very
low jitter (2.5 ps RMS period jitter) makes this chip
ideal for applications requiring low current frequency
sources, such as handheld devices.
