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 12kHz to 20MHz.
4) Tpd is phase shift between the falling edge of pin 3 at 2.0 V and the rising edge of pin 1 at 2.01 V.
Test Circuit uses a split supply of
+2V and -1.3V for ease of testing.
