Table 5. MAX19712 Tx, Rx, and FD Control Using SPI Commands
DA0–DA9 are internally pulled to OVDD. The Rx ADC dig-
ital bus is active and the ADC core is fully operational.
In FAST mode, the switching time from Tx to Rx, or Rx to
Tx is minimized because the converters are on and do
not have to recover from a power-down state. In FAST
mode, the switching time from Rx to Tx and Tx to Rx is
0.1s. Power consumption is higher in FAST mode
because both Tx and Rx cores are always on.
In SLOW Tx mode, the Rx ADC core is powered off and
the ADC digital outputs AD0–AD9 are tri-stated. The Tx
DAC digital bus is active and the DAC core is fully oper-
ational. In SLOW Rx mode, the Tx DAC core is powered
off. The Tx DAC outputs are set to 0. In SLOW Rx mode,
the Tx DAC input bus is disconnected from the DAC
core and DA0–DA9 are internally pulled to OVDD. The
Rx ADC digital bus is active and the ADC core is fully
operational. The switching times for SLOW modes are
5.1s for Rx to Tx and 7.5s for Tx to Rx.
Power consumption in SLOW Tx mode is 33.9mW, and
39.9mW in SLOW Rx mode. Power consumption in FAST
Tx mode is 49.2mW, and 47.4mW in FAST Rx mode.
