Notes:
1.
The symbols used for timing specifications follow the pattern t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tHIKHOX symbolizes the output internal
timing (HI) for the time tserial memory clock reference (K) goes from the high state (H) until outputs (O) are invalid (X).
2.
Output values are based on 30 pF capacitive load.
3.
Inputs are referenced to the sampling that the TDM is programmed to use. Outputs are referenced to the programming edge
they are programmed to use. Use of the rising edge or falling edge as a reference is programmable. TDMxTCK and TDMxRCK are
shown using the rising edge.
4.
All values are based on a maximum TDM interface frequency of 62.5 MHz.
