10.APPENDIX C: PLL FILTER
The PLL has been designed to only use the preambles of the S/PDIF stream to provide lock update information to
the PLL. This results in the PLL being immune to data-dependent jitter effects because the S/PDIF preambles do
not vary with the data.
The PLL has the ability to lock onto a wide range of input sample rates with no external component changes. The
nominal center sample rate is the sample rate that the PLL first locks onto upon application of an S/PDIF data
stream.
