ALL T1/E1 Mode
To reduce system noise and power consumption, the XRT83SH314 offers an ALL T1/E1 mode. Since most
line card designs are configured to operate in T1 or E1 only, the LIU can be selected to shut off the timing
references for the mode not being used by programming the appropriate global register. By default the ALL
T1/E1 mode is enabled (ALLT1/E1 bit = "0"). If the LIU is configured for T1, all E1 clock references and the
8kHz reference are shut off internally to the chip. This reduces the amount of internal clocks switching within
the LIU, hence reducing noise and power consumption. In E1 mode, the T1 clock references are internally
shut off, however the 8kHz reference is available. To disable this feature, the ALLT1/E1 bit must be set to a "1"
in the appropriate global register.

RECEIVE PATH LINE INTERFACE
The receive path of the XRT83SH314 LIU consists of 14 independent T1/E1/J1 receivers. The following
section describes the complete receive path from RTIP/RRING inputs to RCLK/RPOS/RNEG outputs. A
simplified block diagram of the receive path is shown in
Figure 3
