LOOP-BACK MODES
The XRT83L34 supports several Loop-Back modes under both Hardware and Host control. In Hardware
mode the two LOOP[1:0] pins control the Loop-Back functions for each channel independently according to
In Host mode the Loop-Back functions are controlled by the three LOOP[2:0] interface bits. Each channel can
be programmed independently according to Table 15.
LOCAL ANALOG LOOP-BACK (ALOOP)
With Local Analog Loop-Back activated, the transmit data at TTIP and TRING are looped-back to the analog
input of the receiver. External inputs at RTIP/RRING in this mode are ignored while valid transmit data
continues to be sent to the line. Local Analog Loop-Back exercises most of the functional blocks of the
XRT83L34 including the jitter attenuator which can be selected in either the transmit or receive paths. Local
Analog Loop-Back is shown in Figure 20.
In this mode, the jitter attenuator (if selected) can be placed in the transmit or receive path.
