Please contact factory for full Wavecrest characterization. RMS jitter bandwidth of 12kHz to 20MHz. 4) Internal high frequency power source decoupling. 5) Open to enable pin also enables the output. 6) Tpd is phase shift between the falling edge of pin 4 at 2.0V and the rising edge of pin 5 at 2.01V. 7) Logic levels are dependant on specified load of 50 ohms to VCC-2 volts.
