PL602-03 PL602-03 Low Phase Noise CMOS XO (48MHz to 100MHz) FEATURES PIN CONFIGURATION Low phase noise XO output for the 48MHz to 100MHz range (-130 dBc at 10kHz offset). CLK GND 1 8 12 to 25MHz crystal input. VDD 2 7 GND Integrated crystal load capacitor: no external load capacitor required. OE 3 6 N/C Selectable High Drive (30mA) or Standard Drive XIN 4 5 XOUT (10mA) output. 3.3V operation. Note: denotes internal pull up Available in 8-Pin TSSOP or SOIC. OUTPUT RANGE DESCRIPTION FREQUENCY OUTPUT The PL602-03 is a low cost, high performance and MULTIPLIER RANGE BUFFER low phase noise XO, providing less than -130dBc at X4 48 - 100MHz CMOS 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).
