ONCEALMENT
A 1-sample linear interpolator becomes active if a single
sample is flagged as erroneous but cannot be corrected.
The erroneous sample is replaced by a level midway
between the preceding and following samples. Left and
right channels have independent interpolators.
If more than one consecutive non-correctable sample is
found the last good sample is held. A 1-sample linear
interpolation is then performed before the next good
sample (see Fig.5).
DAC Interface
The SAA7335 is compatible with a wide range of ROM
block decoders and Digital-to-Analog Converters DACs.
The seven main formats that are supported are given in
Table 3.

Notes
1.
EIAJ is the abbreviation for Electronic Industries
Associated of Japan.
Number of BCLK periods per half WCLK period
(i.e. bits per sample).
Clock gating must be DISABLED for format mode 7.
