Divide-by-512 Frequency Output, Crystal Oscillator Module IC

OVERVIEW

The CF5029A is crystal oscillator module IC with divide-by-512 frequency output. It employs a

16.777216MHz fundamental frequency crystal source oscillator to generate a 32.768kHz output crystal oscil-

lator with excellent temperature characteristics.
