THREE-WIRE SERIAL AUDIO PORTS
A 3-wire serial audio input port and a 3-wire serial audio output port is provided. Each port can be adjusted to suit
the attached device via control registers. The following parameters are adjustable: master or slave, serial clock fre-
quency, audio data resolution, left or right justification of the data relative to left/right clock, optional 1-bit cell delay
of the 1st data bit, the polarity of the bit clock and the polarity of the left/right clock. By setting the appropriate control
bits, many formats are possible.
Figure 17 shows a selection of common input formats, along with the control bit settings. The clocking of the input
section of the CS8420 may be derived from the incoming ILRCK word rate clock, using the on-chip PLL. The PLL
operation is described in the AES receiver description on page 22. In the case of use with the serial audio input port,
the PLL locks onto the leading edges of the ILRCK clock.
Figure 18 shows a selection of common output formats, along with the control bit settings. A special AES3 direct
output format is included, which allows serial output port access to the V, U, and C bits embedded in the serial audio
data stream. The P bit is replaced by a bit indicating the location of the start of a block. This format is only available
when the serial audio output port is being clocked by the AES3 receiver-recovered clock. Also, the received-channel
status block start signal is only available in Hardware mode 5, as the RCBL pin.
In Master mode, the left/right clock and the serial bit clock are outputs, derived from the appropriate clock domain
master clock.
In Slave mode, the left/right clock and the serial bit clock are inputs. The left/right clock must be synchronous to the
appropriate master clock, but the serial bit clock can be asynchronous and discontinuous if required. By appropriate
phasing of the left/right clock and control of the serial clocks, multiple CS8420’s can share one serial port. The
left/right clock should be continuous, but the duty cycle does not have to be 50%, provided that enough serial clocks
are present in each phase to clock all the data bits. When in Slave mode, the serial audio output port must be set to
left-justified or IS data.
When using the serial audio output port in Slave mode with an OLRCK input which is asynchronous to the port’s
data source, then an interrupt bit is provided to indicate when repeated or dropped samples occur.
The CS8420 allows immediate mute of the serial audio output port audio data via a control register bit.
