Test Condition
1. RCLK duty cycle widths will vary depending on extent of received pulse jitter displacement. Maximum and
minimum RCLK duty cycles are for worst case jitter conditions (0.2UI displacement for E1 per ITU G.823).
2. Clock recovery is disabled in this mode.
3. If MCLK = H the receive PLLs are replaced by a simple EXOR circuit.
4. For all digital outputs.
