Figure 4 shows the relationship between the clock, input
data, and analog outputs. Data for the I channel is
latched on the falling edge of the clock signal, and Q-
channel data is latched on the rising edge of the clock
signal. Both I and Q outputs are simultaneously updated
on the next rising edge of the clock signal.

The 3-wire serial interface controls the MAX5866 opera-
tion modes. Upon power-up, the MAX5866 must be pro-
grammed to operate in the desired mode. Use the 3-wire
serial interface to program the device for the shutdown,
idle, standby, Rx, Tx, or Xcvr mode. An 8-bit data register
sets the operation modes as shown in Table 3. The serial
interface remains active in all six modes.
