Parameter
Output Valid Delay from rising
edge of BIT_CLK
Note 1: Timing is for SDATA and SYNC outputs with respect to BIT_CLK at the device driving the output
Note 2: 50pF external load
Input Setup to falling edge of
BIT_CLK
Input Hold from falling edge of
BIT_CLK
Note: Timing is for SDATA and SYNC outputs with respect to BIT_CLK at the device driving the output
BIT_CLK combined rise or fall
plus flight time
SDATA combined rise or fall
plus flight time
Note: Combined rise or fall plus flight times are provided for worst case scenario modeling purposes
