XR-T5682 Datasheet | Exar

DESCRIPTION The XR-T5682 is a bipolar monolithic voltage controlled crystal oscillator IC designed for general purpose crystal phase locked loop (Pll) and particularly in data rate conversion, jitter reduction, and down multiplexing applications in PCM systems operating at 1.536, 1.544 and 2.048 M/bits/s data rates. It is packaged in 18 pin CERDIP and can operate from 4.75 to 5.25 volts. FUNCTIONAL BLOCK DIAGRAM CRYSTAL TERMINAL 1 TIMING RES.
