What is the process of the ADC after a re-synchronization event, specifically regarding filter settling times and sample collection delay? I need to re-synch to an external event on a regular interval, is there a delay like what happens after a reset?
"The start-up process following a RESET command or a pin reset using the SYNC/RESET pin is similar to what occurs after power up. However there is no tPOR in the case of a command or pin reset because the supplies are already ramped. After reset, the device waits for the initial wait time delay of (256 + 44) × tMOD before providing modulator samples to the two digital filters. The fast-settling filter is enabled for the first two output samples. "
Also:
"The sinc3 and sinc3 + sinc1 filters for a given channel require time to settle after a channel is enabled, the channel multiplexer or gain setting is changed, or a resynchronization event occurs. Table 8-5 lists the settling times of the sinc3 and sinc3 + sinc1 filters for each OSR setting. The ADS130B04-Q1 does not gate unsettled data. Therefore, the host must account for the filter settling time and disregard unsettled data if any are read. The data at the next DRDY falling edge after the filter settling time listed in Table 8-5 has expired can be considered fully settled "
So my understanding is that there is a specified settling time according to Table 8-5 but no delay after a re-sync?
