Footnotes:
1) Standard frequency stability (±20,±25,±50ppm & others available)
2) VOL, VOH, referenced to ground
3) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization.
RMS jitter bandwidth of 12kHz to 20MHz.
4) Open to Enable pin also enables to output.
