6.8
OMCK/PLL_CLK Ratio (address 07h) (Read Only)
6.8.1
OMCK/PLL_CLK RATIO (RATIOX)
Default = xxxxxxxx
Function:
This register allows the user to find the exact absolute frequency of the recovered MCLK coming from
the PLL. This value is represented as an integer (RATIO7:6) and a fractional (RATIO5:0) part. For
example, an OMCK/PLL_CLK ratio of 1.5 would be displayed as 60h.
6.9
RVCR Status (address 08h) (Read Only)
6.9.1
DIGITAL SILENCE DETECTION (DIGITAL SILENCE)
Default = x
0 - Digital Silence not detected
1 - Digital Silence detected
Function:
The CS42526 will auto-detect a digital silence condition when 1548 consecutive zeros have been de-
tected.
6.9.2
AES FORMAT DETECTION (AES FORMATX)
Default = xxx
Function:
The CS42526
will auto-detect the AES format of the incoming S/PDIF stream and display the infor-
mation according to the following table.
