13 / 32 page ADXRS453 Rev. 0 | Page 13 of 32 ADXRS453 SIGNAL CHAIN TIMING The ADXRS453 primary signal chain is shown in Figure 28. The signal chain is the series of necessary functional circuit blocks through which the rate data is generated and processed. This sequence of electromechanical elements determines how quickly the device can translate an external rate input stimulus to an SPI word that is sent to the master device. The group delay, which is a function of the filter characteristic, is the time required for the output of the low-pass filter to be within 10% of the external rate input. In Figure 28, the group delay is shown to be ~4 ms. Additional delay can be observed due to the timing of SPI transactions and the population of the rate data into the internal device registers. Figure 28 illustrates this delay through each element of the signal chain.
