4-Bit Control Mode

When operating in 4-bit control mode, the master device

must be configured as MODE 2 (S2 = 1, S1 = 0) and the

slave device must be configured as MODE 1 (S2 = 0, S1

= 1). When operating in this mode, 24 data and control

bits can be sent from the master to the slave and 20 data

bits can be sent from the slave to the master. Unidirec-

tional control signals should be connected to DP[21:24].

2-Bit Control Mode

When operating in 2-bit control mode, both devices must

be configured in MODE 3 (S2 = S1 = “1”). In this mode,

22 bits can be sent in either direction. When operating in

a 2-bit control mode, serialized bits 21 and 22 appear on

outputs 23 and 24 of the deserializer.

Power-Down Mode: (Mode 0)

Mode 0 is used for powering down and resetting the

device. When both of the mode signals are driven to a

LOW state, the PLL and references are disabled, differ-

ential input buffers are shut off, differential output buffers

are placed into a HIGH-impedance state, LVCMOS out-

puts are placed into a HIGH-impedance state, LVCMOS

inputs are driven to a valid level internally, and all inter-

nal circuitry is reset. The loss of CKREF state is also

enabled to ensure that the PLL only powers up if there is

a valid CKREF signal.

In a typical application, the device only changes between

the power-down mode and the selected mode of opera-

tion. This allows for system-level power-down functional-

ity to be implemented via a single wire for a SerDes pair.

The S1 and S2 selection signals that have their operat-

ing mode driven to a “logic 0” should be hardwired to

GND. The S1 and S2 signals that have their operating

mode driven to a “logic 1” should be connected to a

system level power-down signal.
