Table-67 Transmitter and Receiver Timing Characteristics
1.Relative to nominal frequency, MCLK= ± 100 ppm
2.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
3.For all digital outputs. C load = 15pF
