However, power consumption is higher in this mode
because both the Tx and Rx cores are always on. To
prevent bus contention in these states, the Rx ADC out-
put buffers are tri-stated during Tx and the Tx DAC
input bus is tri-stated during Rx.
In SLOW mode, the Rx ADC core is off during Tx; like-
wise the Tx DAC and filters are turned off during Rx to
yield lower power consumption in these modes. For
example, the power in SLOW Tx mode is 49.5mW. The
power consumption during Rx is 77.1mW compared to
84.6mW power consumption in FAST mode. However,
the recovery time between states is increased. The
switching time in SLOW mode between Rx to Tx is 7s
and Tx to Rx is 4.1s.
External T/R
R Switching Control vs.
Serial-Interface Control
Bit E3 in the ENABLE-16 or ENABLE-8 register deter-
mines whether the device Tx-Rx mode is controlled
externally through the T/R input (E3 = low) or through the
SPI command (E3 = high). By default, the MAX19707 is
in the external Tx-Rx control mode. In the external control
mode, use the T/R input (pin 27) to switch between Rx
and Tx modes. Using the T/R pin provides faster switch-
ing between Rx and Tx modes. To override the external
Tx-Rx control, program the MAX19707 through the serial
interface. During SHDN, IDLE, or STBY modes, the T/R
input is overridden. To restore external Tx-Rx control,
program bit E3 low and exit the SHDN, IDLE, or STBY
modes through the serial interface.
SPI Timing
The serial digital interface is a standard 3-wire connec-
tion compatible with SPI/QSPI/MICROWIRE/DSP inter-
faces. Set CS low to enable the serial data loading at
DIN or output at DOUT. Following a CS high-to-low tran-
sition, data is shifted synchronously, most significant bit
first, on the rising edge of the serial clock (SCLK). After
16 bits are loaded into the serial input register, data is
transferred to the latch when CS transitions high. CS
must transition high for a minimum of 80ns before the
next write sequence. The SCLK can idle either high or
low between transitions. Figure 6 shows the detailed
timing diagram of the 3-wire serial interface.
