Footnotes:
1) Standard frequency stability (±20,±25,±50ppm & others available)
2) V_OL, V_OH, referenced to ground (V_EE) with V_CC = 2.5V
3) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization.
RMS jitter bandwidth of 12kHz to 20MHz.
4) Tpd is phse shift between the falling edge of pin 4 at 2.0V and the rising edge of pin 5 at 2.01V.
5) Open to enable pin also enables the output.
6) Internal high frequency power source decoupling.
