Transmit Path
Receive Path
Note:
1. Relative to nominal frequency, MCLK = +100 or -100 ppm.
2. RCLK duty cycle width will vary depending on extent of the received pulse jitter displacement. Maximum and minimum RCLK duty cycles are for worst case jitter conditions (0.2 UI
displacement for E1 per ITU G.823).
3. For all digital outputs. C
