Bit 0: Transmit Power-Down (TPD)
0 = powers down the transmitter and three-states the TTIP and TRING pins
1 = normal transmitter operation
Bit 1: Disable Jitter Attenuator (DJA)
0 = jitter attenuator enabled
1 = jitter attenuator disabled
Bit 2/Jitter Attenuator Buffer Depth Select (JABDS)
0 = 128 bits
1 = 32 bits (use for delay-sensitive applications)
Bit 3: Jitter Attenuator Select (JAS)
0 = place the jitter attenuator on the receive side
1 = place the jitter attenuator on the transmit side
Bit 4: Receive Equalizer Gain Limit (EGL). This bit controls the sensitivity of the receive equalizer.
T1 Mode: 0 = -36dB (long haul)
1 = -15dB (limited long haul)
E1 Mode: 0 = -43dB (long haul)
1 = -12dB (short haul)
Bits 5, 6, 7: Line Build-Out Select (L0 to L2). When using the internal termination, the user needs only to select 000 for 75
operation or 001 for 120 operation. This selects the proper voltage levels for 75 or 120 operation. Using TT0, TT1, and
TT2 of the LICR4 register, users can then select the proper internal source termination. Line build-outs 100 and 101 are for
backwards compatibility with older products only.
