QRSS/PRBS Select Bits
These bits are used to select between QRSS and PRBS.

PRBS Receive/Transmit Select:
This bit is used select where the output of the PRBS Generator is
directed.
0 = PRBS Generator is output on TTIP and TRING
1 = PRBS Generator is output on RPOS and RCLK

Receiver ON:
This bit permits the user to either turn on or turn off the Receive Sec-
tion of XRT86VL38. If the user turns on the Receive Section, then
XRT86VL38 will begin to receive the incoming data-stream via the
RTIP and RRING input pins.
Conversely, if the user turns off the Receive Section, then the entire
Receive Section except the MCLKIN Phase Locked Loop (PLL) will
be powered down.
0 = Shuts off the Receive Section of XRT86VL38.
1 = Turns on the Receive Section of XRT86VL38.

Equalizer Control [4:0]:
These bits are used to control the transmit pulse shaping, transmit
line build-out (LBO) and receive sensitivity level.
The Transmit Pulse Shape can be controlled by adjusting the Trans-
mit Line Build-Out Settings for different cable length in T1 mode.
Transmit pulse shape can also be controlled by using the Arbitrary
mode, where users can specify the amplitude of the pulse shape by
using the 8 Arbitrary Pulse Segments provided in the LIU registers
(0x0Fn8-0xnFnF), where n is the channel number.
The XRT86VL38 device supports both long haul and short haul
applications which can also be selected using the EQC[4:0] bits.
Table 109
.presents the corresponding Transmit Line Build Out and
Receive Sensitivity settings using different combinations of these
five EQC[4:0] bits.
