AUXEN
I/O
Extended audio enable. When HIGH, the GS9023A processes 24-bit audio
samples. When LOW, the GS9023A processes 20-bit samples. In Multiplex
Mode, this pin is an input and is supplied by the user. The setting is logical OR
with the related A4ON setting in host interface register address 1h. In
Demultiplex Mode, this pin is an output and is generated by the GS9023A.
39, 51, 67, 76
VDDIO
+3.3V or +5V power supply pins for device I/Os. In order for device I/O to be +5V
tolerant V
DDIO
must be +5V. Device I/O are not +5V tolerant if V
DDIO
is +3.3V.
40-48
PKT[8:0]
I/O
Arbitrary data I/O bus. In Multiplex Mode, the user must input the arbitrary data
packet words starting from the secondary data identification (SDID) to the last
user data word (UDW) according to SMPTE 291M. The GS9023A internally
converts the data to 10 bits by generating the inversion bit (bit 9). The checksum
(CS) word is also generated internally. In Demultiplex Mode, the GS9023A
outputs the arbitrary data packet words starting from the SDID to the last UDW.
PKT[8] is the MSB and PKT[0] is the LSB. See Figure 11 and Figure 16.
49
PKTEN
I/O
Arbitrary data packet enable. In Multiplex Mode, PKTEN must be set HIGH one
PCLK cycle before Arbitrary packet data is input to the device. In Demultiplex
Mode, the output is set HIGH when outputting Arbitrary packet data. See Figure
11 and Figure 16.
52, 69
NC
N/A
No Connect. Do not connect these pins.
53
WCOUT
O
48kHz word clock for channels 1, 2, 3 and 4. Valid only when operating in
Demultiplex Mode.
54
AOUTB
O
Audio signal output for channels 3 and 4. The AES/EBU digital audio output is bi-
phase mark encoded. In all non-AES/EBU modes, the output is not bi-phase
mark encoded.
55
AOUTA
O
Audio signal output for channels 1 and 2. The AES/EBU digital audio output is bi-
phase mark encoded. In all non-AES/EBU modes, the output is not bi-phase
mark encoded.
56, 57, 59-66
DOUT[9:0]
O
Parallel digital video signal output. DOUT[9] is the MSB and DOUT[0] is the LSB.
68
LOCK
O
Lock indicator. In Multiplex Mode, when HIGH, the video standard has been
identified, the start of a new video frame has been detected and the device is
multiplexing audio.
NOTE: LOCK will not be set HIGH unless at least one of the audio channel
enable bits is HIGH. See “CHACT” description in Table 14.
In Demultiplex Mode, when HIGH, the video standard has been identified, the
‘lock’ process selected by “ACTSEL” has been validated and the device is
demultiplexing audio. See “ACTSEL” description in Table 15.
NOTE: LOCK remains active regardless of the number of audio samples in the
video stream after ‘lock’ is achieved.
70
BUFERR
O
Buffer error. Indicates when an internal buffer overflow/underflow error has
occurred. Valid only when the device is configured to operate in Demultiplex
Mode.
NOTE: If an internal buffer overflow/underflow condition occurs, the GS9023A
does not mute the audio output.
