MCLK Frequency
MCLK Duty Cycle
MCLK Jitter (In-band or aliased in-band)
MCLK Jitter (Out-of-band)
Rise Times:
Fall Times:
MSYNC Setup Time to MCLK falling
MSYNC Hold Time after MCLK falling
MCLK rising to Valid MFLAG
MCLK rising to Valid MDATA
= 0V or -2.5V ± 5%; VD = +5V or +3.3V ± 5%; Digital Inputs: Logic 0 = 0V, Logic 1 = VD; C
18. Excludes MCLK input, MCLK should be driven with a signal having rise/fall times of 25 ns or faster.
19. MSYNC latched on MCLK falling edge, data output on next MCLK rising edge.
