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 MAX5863 opera-
tion modes. Upon power-up, the MAX5863 must be
programmed 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.
