Footnotes:
1) Standard frequency stability (±20,±25,±50ppm & others available)
2) With Load of 100 ohms across differential outputs.
3) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization.
RMS jitter bandwidth of 12kHz to 20MHz.
4) Tpd is phase shift between the falling edge of pin 7 and the rising edge of pin 8.
5) Open to enable also enables the output.
