Tx DAC Timing
Figure 5 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 MAX19700 oper-
ation modes as well as the three 12-bit aux-DACs. Upon
power-up, program the MAX19700 to operate in the
desired mode. Use the 3-wire serial interface to pro-
gram the device for shutdown, idle, standby, Rx, Tx, or
aux-DAC modes. A 16-bit data register sets the mode
control. The 16-bit word is comprised of A3–A0 control
bits and D11–D0 data bits. Tables 4, 5, and 6 show the
MAX19700 operating modes and SPI commands. The
serial interface remains active in all modes.
Table 2. Tx Path Output Voltage vs. Input Codes
(Internal Reference Mode VREFDAC = 1.024V, External Reference Mode VREFDAC = VREFIN; VFS = 410mV for
820mVP-P Full Scale and VFS = 500mV for 1VP-P Full Scale)
