21 / 54 page ![]() CobraNet Hardware User’s Manual Digital Audio Interface DS651UM23 ©Copyright 2005 Cirrus Logic, Inc. 21 Version 2.3 6.1.1 Normal Mode Data Timing Figure 8. Audio Data Timing Detail - Normal Mode, 64FS - CS18100x/CS49610x, CS18101x/CS49611x Figure 9. Audio Data Timing Detail - Normal Mode, 128FS - CS18102x/CS49612x Each audio channel is comprised of 32 bits of data, regardless of audio sample size. The figure above shows 24-bit audio data. The MSB is left justified and is aligned with FS1. Data is sampled on the rising edge of DAI_SCLK and data changes on the falling edge. 6.1.2 I2S Mode Data Timing Figure 10. Audio Data Timing Detail - I2S Mode, 64FS - CS18100x/CS49610x, CS18101x/CS49611x Figure 11. Audio Data Timing Detail - I2S Mode, 128FS - CS18102x & CS49612x Each audio channel is comprised of 32 bits of data, regardless of audio sample size. The figure above shows 24-bit audio data. The MSB is left justified and arrives one bit period following FS1. Data is sampled on the rising edge of DAI_SCLK and data changes on the falling edge.
