1. Si501 supports OE/mode functionality. Si502 supports OE/mode and FS functionality. Si503 supports only FS functionality. See data
sheet functional description section for more information.
2. Frequency stability includes initial tolerance, solder shift, operating temp range, rated power supply voltage change, load change, 10-year
aging, shock, and vibration.
3. CL = 15 pF, TR/TF (20% to 80%), 3.3 V unless otherwise stated. See datasheet for additional TR/TF options.
4. Recommended series termination resistor (RS) = 24.9 for Z0=50 .
5. Integrated phase jitter exceeds some high-performance data communications system requirements. See AN783 for more information.
