Register Description
This section contains the detailed register descriptions of each bit. Whenever the variable “n” in italics is used in
any of the register descriptions, it represents 1–16. Note that in the register descriptions, there are duplicate
registers for LIUs 1–8 and LIUs 9–16. There are registers in LIUs 1–8 that do not have a duplicate in the register
set for LIUs 9–16. For these registers, only one address is listed. All other registers list two addresses, one for LIUs
1–8 and one for LIUs 9–16.

Bit 7: Device CODE ID Bit 7 (ID7). This bit is “zero” for short-haul operation.
Bits 6 to 3: Device CODE ID Bits 6 to 3 (ID6 to ID3). These bits tell the user the number of ports the device
contains.
Bits 2 to 0: Device CODE ID Bits 2 to 0 (ID2 to ID0). These bits tell the user the revision of the part. Contact the
factory for details.

Bits 7 to 0: Analog Loopback Control Bits Channel n (ALBCn). When this bit is set, LIUn is placed in Analog
Loopback. TTIP and TRING are looped back to RTIP and RRING. The data at RTIP and RRING is ignored. LOS
Detector is still in operation. The jitter attenuator is in use if enabled for the transmitter or receiver.
