• Manufacturer Part Number: LC89075W-H
• Description: Digital Audio Interface Receiver with Stereo ADC and Audio Selector
• Manufacturer: SANYO [Sanyo Semicon Device]

• The non-PCM data is the same as the detection data output on NPCMF.
• When an error is indicated in the RXRESEL register due to non-PCM data, the output data is muted.
• The RXRESTA register has no effect on the data and clock output pins.
• When “RXREFSJ=0”, sources with changing fs (CD players with variable pitch functions, etc.) are supported. If it is
• “RXREFSJ=1” is set that when the change in input fs exceeds the range of the calculation after releasing the error, the
• The RXERWT[1:0] register setting defines the time after the PLL is locked until ERRF outputs “L” to cancel the error.

00: No limitation (initial value)
01: fs ≤ 96kHz (When exceeded, data is muted and XIN system clock is output.)
10: fs ≤ 48kHz (When exceeded, data is muted and XIN system clock is output.)
11: Reserved
00: The error is canceled after 3 occurrences of preamble B are counted (initial value).
01: Error is canceled after 6 occurrences of preamble B are counted.
10: Error is canceled after 12 occurrences of preamble B are counted.
11: Error is canceled after 24 occurrences of preamble B are counted.
0: PLL lock error or data error (initial value)
1: PLL lock error or data error or non-PCM data
0: Output only when non-PCM data is recognized (initial value).
1: Output only during the sub-frame in which error occurred.
0: Always output PLL status (initial value).
1: Forced to error output “H”
0: Input fs change after error is canceled is not reflected to ERRF (initial value).
1: Input fs change after the error is canceled is reflected to ERRF.
