Ordering Information
Appendix A. Transmit Path Group Delay vs. Bit Offset
Receive path group delay is a fixed value and is specified in the data sheet.
Note:
Bit offset values for partial time segments would incrementally add to the base data delay value by 488 ns
per bit offset for an SCK of 2.048 MHz and in increments of 244 ns per bit offset for an SCK of 4.096 MHz.
