PLL602-01 Low Phase Noise XO (24MHz to 50MHz) FEATURES • • • • • Low phase noise XO output for the 24MHz to 50MHz range (-135 dBc at 10kHz offset). 12 to 25MHz crystal input. Integrated crystal load capacitor: no external load capacitor required. Low jitter (RMS): 3ps period jitter (1 sigma). Selectable High Drive (30mA) or Standard Drive (10mA) output. 3.3V operation. Available in 8-Pin TSSOP or SOIC.
