Footnotes:
1) Standard frequency stability (±20, ±25, ±50 ppm & others available).
2) VOL, VOH, referenced to ground (VEE) with VCC = 3.3 V.
3) Jitter performance is frequency dependent. Please contact factory for full Wavecrest characterization. RMS jitter bandwidth of
12 kHz to 20 MHz.
5) Open to enable pin also enables the output.
