DIGITAL CHARACTERISTICS (CONT.)

Notes: 32. MCLK is generated by the CS5378 digital filter. If MCLK is disabled, the device automatically enters a

power-down state.

33. MSYNC is generated by the CS5378 digital filter and is latched on MCLK rising edge, synchronization

instant (t

0

) on next MCLK rising edge.

34. TDATA can be delayed from 0 to 63 full bit periods by the test bit stream generator in the CS5378 digital

filter. The timing diagrams show no TBSDATA delay.

35. Decimated, filtered, and offset corrected 24-bit output word from the CS5378 digital filter.

36. TDATA is generated by the test bit stream generator in the CS5378 digital filter.

37. TBSGAIN register value in the CS5378 digital filter.
