CS8414 DESCRIPTION
The CS8414 does not need a microprocessor to
handle the non-audio data (although a micro may
be used with the C and U serial ports). Instead, ded-
icated pins are available for the most important
channel status bits. The CS8414 is a monolithic
CMOS circuit that receives and decodes digital au-
dio data which was encoded according to the digital
audio interface standards. It contains an RS422 line
receiver and clock and data recovery utilizing an
on-chip phase-locked loop. The audio data is out-
put through a configurable serial port that supports
14 formats. The channel status and user data have
their own serial pins and the validity flag is OR’ed
with the ERF flag to provide a single pin, VERF,
indicating that the audio output may not be valid.
This pin may be used by interpolation filters that
provide error correction. A block diagram of the
CS8414 is illustrated in Figure 16.
The line receiver and jitter performance are de-
scribed in the sections directly preceding the
CS8413 sections in the beginning of this data sheet.
Audio Serial Port
The audio serial port is used primarily to output au-
dio data and consists of three pins: SCK, FSYNC,
and SDATA. These pins are configured via four
control pins: M0, M1, M2, and M3. M3 selects be-
tween eight normal serial formats (M3 = 0), and six
special formats (M3 = 1).
