Description
Comma Detect.
0 = no comma yet detected in the incoming serial stream or receiver PLL not locked.
1 = the receiver PLL is locked and a positive or negative comma bit sequence detected
in the incoming bit stream. The serial to parallel converter is aligned to the proper 10-
bit word boundary when comma alignment is enabled (CALIGN_EN = 1).

Power down control signals.
TXPWDNB
0 = Transmitter is powered down and DOUT± pins are high impedance.
1 = Transmitter is powered up.
RXPWDNB
0 = Receiver is powered down and ROUT [9:0] as well as LOS, LOCKB, CDET,
RXCLK, and SYSCLK are high impedance.
1 = Receiver is powered up.
Comma alignment enable.
0 = comma alignment circuitry disabled. Receiver will not realign 10-bit data based on
incoming comma characters. CDET pin still flags comma detection.
1 = comma detect and alignment circuitry enabled. Receiver aligns 10-bit data to
incoming comma character and flags comma detect through CDET pin.
Receiver recovered clock mode
0 = Write mode. RXCLK pin is a recovered clock output.
(RXCLK = output pin)
1 = Read mode. RXCLK pin is ROUT [9:0] bus read input strobe.
(RXCLK = input pin)
Selects whether single-ended data and control pins are 3.3V LVTTL or 1.8V LVCMOS.
0 = 1.8V LVCMOS. Tie VSEL to ground and power IOVDD at 1.8 V.
1 = 3.3V LVTTL. Tie VSEL to IOVDD supply and power IOVDD at 3.3 V.
Selects SerDes mode.
0 = Base station mode
1 = Reserved for future use
Hardware SerDes reset. Resets PLLs and MDIO registers.
0 = Hardware SerDes reset
1 = Normal operation
