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.
Figure 8
is a
timing diagram of the receive data updated on the rising edge of RCLK.
Figure 9
is a timing diagram of the
receive data updated on the falling edge of RCLK. The timing specifications are shown in

Receive Sensitivity
To meet short haul requirements, the XRT83SH38 can accept T1/E1/J1 signals that have been attenuated by
12dB of flat loss in E1 mode or by 655 feet of cable loss along with 6dB of flat loss in T1 mode. However, the
XRT83SH38 can tolerate cable loss and flat loss beyond the industry specifications. The receive sensitivity in
the short haul mode is approximately 4,000 feet without experiencing bit errors, LOF, pattern synchronization,
etc. Although data integrity is maintained, the RLOS function (if enabled) will report an RLOS condition
