XRT83SH314
14-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
The receive clock (RCLK) is recovered by the clock and data recovery circuitry. An internal PLL locks on the
incoming data stream and outputs a clock that’s in phase with the incoming signal. This allows for multi-
channel T1/E1/J1 signals to arrive from different timing sources and remain independent. In the absence of an
incoming signal, RCLK maintains its timing by using the internal master clock as its reference. The recovered
data can be updated on either edge of RCLK. By default, data is updated on the rising edge of RCLK. To
update data on the falling edge of RCLK, set RCLKE to "1" in the appropriate global register.
