Table 5. MAX19713 Tx, Rx, and FD Control Using SPI Commands

In FAST Rx mode, the Tx DAC core is powered on. The

Tx DAC outputs are set to midscale. In this mode, the Tx

DAC input bus is disconnected from the DAC core and

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

4.9s for Rx to Tx and 3.7s for Tx to Rx.

Power consumption in SLOW Tx mode is 49.5mW, and

79.2mW in SLOW Rx mode. Power consumption in FAST

Tx mode is 89.1mW, and 86.4mW in FAST Rx mode.
