SINGLE CHANNEL T1/E1/J1 LONG HAUL/SHORT HAUL LINE INTERFACE UNIT
Table-62 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 (0.2UI displacement
3.For all digital outputs. C load = 15pF
