TRANSCEIVER TIMING CHARACTERISTICS
IDT82V2048 OCTAL T1/E1 SHORT HAUL LINE INTERFACE UNIT
NOTE:
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 for E1 per ITU G.823).
3. For all digital outputs. C load = 15 pF
4. Clock recovery is disabled in this mode.
