CS8420
AES3/SPDIF Receiver Interface:
RXP, RXN - Differential Line Receiver Inputs
Differential line receiver inputs, carrying AES3 type data.
RMCK - Input Section Recovered Master Clock Output
Input section recovered master clock output. Will be at a frequency of 256x the input sample rate (Fsi).
RERR - Receiver Error Indicator
When high, indicates a problem with the operation of the AES3 receiver. The status of this pin is updated once per
sub-frame of incoming AES3 data. Conditions that cause RERR to go high are: validity, parity error, and bi-phase
coding error, as well as loss of lock in the PLL.
NVERR - No Validity Receiver Error Indicator
When high, indicates a problem with the operation of the AES3 receiver. The status of this pin is updated once per
frame of incoming AES3 data. Conditions that cause NVERR to go high are: parity error, and bi-phase coding error,
as well as loss of lock in the PLL.
EMPH - Pre-emphasis Indicator Output
EMPH is low when the incoming AES3 data indicates the presence of 50/15
μs pre-emphasis. When the AES3 data
indicates the absence of pre-emphasis or the presence of non 50/15
μs pre-emphasis EMPH is high. This is also a
start-up option pin, and requires a pull-up or pull-down resistor.
COPY - Copy Channel Status Bit Output
The COPY pin reflects the state of the COPY Channel Status bit in the incoming AES3 type data stream.
ORIG - Original Channel Status Output
SCMS generation indicator. This is decoded from the incoming category code and the L bit. A low output indicates
that the audio data stream is 1st generation or higher. A high indicates that the audio data stream is original. This is
also a start-up option pin, and requires a pull-up or pull-down resistor.
PRO - Professional Channel Status Bit Output
The PRO pin reflects the state of the Professional/Consumer Channel Status bit in the incoming AES3 type data
stream.
AUDIO - Audio Channel Status Bit Output
The AUDIO pin reflects the state of the audio/non audio Channel Status bit in the incoming AES3 type data stream.
RCBL - Receiver Channel Status Block Output
RCBL indicates the beginning of a received channel status block. RCBL goes high 2 frames after the reception of a
Z preamble, remains high for 16 frames while COPY, ORIG, AUDIO, EMPH and PRO are updated, and returns low
for the remainder of the block. RCBL changes on rising edges of RMCK.
CHS - Channel Select Input
Selects which sub-frame’s channel status data is output on the EMPH, COPY, ORIG, PRO and AUDIO pins. Chan-
nel A is selected when CHS is low, channel B is selected when CHS is high.
U - User Data Output
The U pin outputs user data from the AES3 receiver, clocked by rising and falling edges of OLRCK.
C - Channel Status Data Output
The C pin outputs channel status data from the AES3 receiver, clocked by rising and falling edges of OLRCK.
