PL602-03

PL602-03 Low Phase Noise CMOS XO (48MHz to 100MHz) FE AT UR E S  Low phase noise XO output for the 48MHz to 100MHz range (-130 dBc at 10kHz offset).  12 to 25MHz crystal input.  Integrated crystal load capacitor: no external load capacitor required.  Selectable High Drive (30mA) or Standard Drive (10mA) output.  3.3V operation.  Available in 8-Pin TSSOP or SOIC. DESCRIPTION The PL602-03 is a low cost, high performance and low phase noise XO, providing less than -130dBc at 10kHz offset in the 48MHz to 100MHz operating range. The very low jitter makes this chip ideal for applications requiring clean reference frequency sources. Input crystal can range from 12 to 25MHz (fundamental resonant mode).
