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. Following a CS high-to-low transition, data is shift-
ed 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 transi-
tions. Figure 6 shows the detailed timing diagram of the
3-wire serial interface.
Mode-Recovery Timing
Figure 7 shows the mode-recovery timing diagram.
tWAKE is the wakeup time when exiting shutdown, idle,
or standby mode and entering Rx or Tx mode. tENABLE
is the recovery time when switching between either Rx
or Tx mode. tWAKE or tENABLE is the time for the Rx ADC
to settle within 1dB of specified SINAD performance and
Tx DAC settling to 10 LSB error. tWAKE and tENABLE
times are measured after either the 16-bit serial com-
mand is latched into the MAX19700 by a CS transition
high (SPI controlled) or a T/R logic transition (external
Tx-Rx control). In FAST mode, the recovery time is 1s
to switch between Tx or Rx modes.
