MAX5865
DAC Timing
Figure 4 shows the relationship between the clock, input
data, and analog outputs. Data for the I channel (ID) is
latched on the falling edge of the clock signal, and Q-
channel (QD) 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.
3-Wire Serial Interface and
Operation Modes
The 3-wire serial interface controls the MAX5865 opera-
tion modes. Upon power-up, the MAX5865 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.
