5.1 Register Description
This section details the register description of each bit. Whenever the variable ‘
n’
in italics is used in any of the
register descriptions, it represents 1, 2, 3, 4, 5, 6, 7, and 8.

Register Address:
Bit #
Name
Bit 7: Device CODE ID Bit 7 (ID7).
This bit is zero for the 75 impedance part number and one for the 120
impedance part number.
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.

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.

. The analog-received signal goes through the receive digital and is looped back to the
transmitter. The data at TPOS and TNEG is ignored. The jitter attenuator is in use if enabled.
