DIGITAL SIGNAL PROCESSOR FOR DISCMAN
20
INTERPOLATOR / MUTE
Interpolator
If a burst error occurs on the disc, sometimes data cannot be corrected even if you carry out the ECC process. The
Interpolator block uses the ECCs C2 pointer to interpolate the data.
The audio data is input into the Data bus in the following order: for each L/R-ch: 8-bit C2 point, lower data 8 bits,
and upper data 8 bits.
If C2PO pin is high, and one error has occurred, the average value interpolation is carried out, and if three
consecutive errors occurred, the previous value hold interpolation is carried out.
For one period of LRCH, if LRCH is low, R-ch data is output, and if LRCH is high, L-ch data is output. Please refer
to Figure-9 for the Interpolator blocks timing diagram.
