Description
TXBST
0x14[7]
WO
Transmit Boost
Used in conjunction with DAA to manage transmit level. If set to 1,
Transmit signal is increased by 6 dB. See Section 9.3.1.
DAA
0x14[6:5]
WO
DAA Tx Gain
Used in conjunction with TXBST to manage transmit level. See
Section 9.3.1.
RXBST
0x14[3]
W
Received Boost
If set to 1, Receive signal is increased by 20 dB.
Default is 0.
RXG
0x14[1:0]
WO
Receive Gain
Sets the receive path gain/attenuation. See Table 41.
TXEN
0x16[7]
WO
Transmit Path Enable
1 = Enable Transmit Path.
0 = Disable Transmit Path. (Default)
RXEN
0x16[6]
WO
Receive Path Enable
1 = Enable Receive Path.
0 = Disable Receive Path. (Default)
9.3.1
Transmit and Receive Level Control
On the transmit side, 0 dBm transmit programming at the MAFE interface results in ~0 dBm on the line. On
the receive side, 0 dBm receive signal on the line results in ~0 dBm at the MAFE interface.
On the transmit side there are three bits to adjust the transmit level: TXBST (Register 0x14[7]), DAA(1:0)
(Register 0x14[6:5]).
