EXPANDED REGISTER DESCRIPTION
e-AFE: AFE Enable Selection Register (R/W, Expanded Address = 02H)
Symbol
Position
Default
Description
AFE[7:0]
AFE.7-0
00H(1)
1. In host mode, AFE[7:0] bits must be set to ‘FFH’ for normal device operation.
0 = Reserved (Default) Note: For remote loopback operation in G.772 monitoring mode, bit 0 can be set to '0'.
1 = AFE mode enabled.
e-RPDN: Receiver n Powerdown Register (R/W, Expanded Address = 03H)
Symbol
Position
Default
Description
RPDN[7:0]
RPDN.7-0
00H
0 = Normal operation. (Default)
1 = Receiver n is powered down.
e-TPDN: Transmitter n Powerdown Register (R/W, Expanded Address = 04H)
Symbol
Position
Default
Description
TPDN[7:0]
TPDN.7-0
00H
0 = Normal operation. (Default)
1 = Transmitter n is powered down(1) (the corresponding transmit output driver enters a low power high impedance mode).
1. Transmitter n is powered down when either pin TCLKn is pulled low or TPDNn is set to ‘1’
e-EQUA: Receive Equalizer Enable/Disable Register (R/W, Expanded Address = 07H)
Symbol
Position
Default
Description
EQUA[7:0]
EQUA.7-0
00H
0 = Normal operation. (Default)
1 = Equalizer in Receiver n is enabled, which can improve the receive performance when transmission length is more than
200 m.
