PCM3052A
SLES160 – NOVEMBER 2005
Each bit after the audio sample word is assigned in the PCM3052A as follows.
Validity bit:
Writable through serial control port
User data:
Fixed to 0
Channel status [0]:
Fixed to 0 (consumer use)
Channel status [1]:
Writable through serial control port (audio sample word type)
Channel status [2]:
Writable through serial control port (copyright flag)
Channel status [3:5]:
Writable through serial control port (additional format information)
Channel status [6:7]:
Fixed to 00 (mode 0)
Channel status [8:15]:
Writable through serial control port (category code)
Channel status [16:19]:
Fixed to 0000 (source number)
Channel status [20:23]:
Fixed to 0000 (channel number)
Channel status [24:27]:
Writable through serial control port (sampling frequency)
Channel status [28:29]:
Writable through serial control port (clock accuracy)
Channel status [30:31]:
Fixed to 00
Channel status [32:35]:
Writable through serial control port (word length)
Channel status [36:191]:
Fixed to all 0s
Parity bit:
Even parity for preceding data from preamble to channel status bit
S/PDIF output timing is shown in Figure 51. The S/PDIF block starts with a preamble after 32/fS from the frame
where S/PDIF output control bit becomes HIGH. The behavior of DOUTS for power-on reset, external reset, and
loss of synchronization is shown in Figure 44, Figure 45, and Figure 48, respectively.
