Footnotes: 1) Standard frequency stability (±20,±25,±50ppm & others available) 2) VOL, VOH, referenced to ground (VEE) with VCC = 3.3V 3) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization. 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.
