Jitter Attenuator
The XRT83SH314 LIU is ideal for multiplexer or mapper applications where the network data crosses multiple
timing domains. As the higher data rates are de-multiplexed down to T1 or E1 data, stuffing bits are typically
removed which can leave gaps in the incoming data stream. The jitter attenuator can be selected in the
transmit path with a 32-Bit or 64-Bit FIFO that is used to smooth the gapped clock into a steady T1 or E1
output. The maximum gap width of the 14-Channel LIU is shown in Table 9.
NOTE: If the LIU is used in a loop timing system, the jitter attenuator can be selected in the receive path. See the Receive
Section of this datasheet.
3.4
TAOS (Transmit All Ones)
The XRT83SH314 has the ability to transmit all ones on a per channel basis by programming the appropriate
channel register. This function takes priority over the digital data present on the TPOS/TNEG inputs. For
example: If a fixed "0011" pattern is present on TPOS in single rail mode and TAOS is enabled, the transmitter
will output all ones. In addition, if digital or dual loopback is selected, the data on the RPOS output will be
equal to the data on the TPOS input. Figure 18 is a diagram showing the all ones signal at TTIP and TRING.

Transmit Diagnostic Features
In addition to TAOS, the XRT83SH314 offers multiple diagnostic features for analyzing network integrity such
as ATAOS and QRSS on a per channel basis by programming the appropriate registers. These diagnostic
features take priority over the digital data present on TPOS/TNEG inputs. The transmitters will send the
diagnostic code to the line and will be maintained in the digital loopback if selected.
When the LIU is
responsible for sending diagnostic patterns, the LIU is automatically placed in the single rail mode.
