VDD
-
+3.3V power supply pins.
2
AIN7/8
I
Audio signal input for channels 7 and 8. AES/EBU digital audio data is bi-phase mark
encoded. For all non-AES/EBU input modes, bi-phase mark encoding is not required.
3
AIN5/6
I
Audio signal input for channels 5 and 6. AES/EBU digital audio data is bi-phase mark
encoded. For all non-AES/EBU input modes, bi-phase mark encoding is not required.
4
AIN3/4
I
Audio signal input for channels 3 and 4. AES/EBU digital audio data is bi-phase mark
encoded. For all non-AES/EBU input modes, bi-phase mark encoding is not required.
5
AIN1/2
I
Audio signal input for channels 1 and 2. AES/EBU digital audio data is bi-phase mark
encoded. For all non-AES/EBU input modes, bi-phase mark encoding is not required.
6
WCINB
I
48kHz word clock for channels 5 to 8. Used only when operating in Multiplex Mode and
when the audio source is not an AES/EBU data stream. This pin should be grounded
when inputting AES/EBU digital audio data or when operating in Demultiplex Mode
(DEC_MODE set LOW).
7
WCINA
I
48kHz word clock for channels 1 to 4. Used only when operating in Multiplex Mode and
when the audio source is not an AES/EBU data stream. This pin should be grounded
when inputting AES/EBU digital audio data or when operating in Demultiplex Mode
(DEC_MODE set LOW).
8
DSCBYPASS
I
Descrambler bypass. When set LOW, the internal SMPTE 292M descrambler is enabled.
When set HIGH, the internal SMPTE 292M descrambler is bypassed. The video input to
the device must be word aligned.
9
PLLCNTB
O
Audio clock PLL control signal for channels 5 to 8.
10
PLLCNTA
O
Audio clock PLL control signal for channels 1 to 4.
11
CASCADE
I
Cascade mode select. When set HIGH, the GS1503 will default to audio groups 3 and 4.
Two GS1503 devices can then be cascaded in series to allow up to 16 channels of audio
to be multiplexed or demultiplexed (only one device requires CASCADE to be set HIGH).
When set LOW, the GS1503 will default to audio groups 1 and 2.
12
MUTE
I
Audio mute. In Multiplex Mode, when set HIGH, the embedded audio packets are forced
to '0'. In Demultiplex Mode, when set HIGH, the audio output data is forced to "0".
13
ANCI
I
Ancillary data delete select. Valid in Demultiplex Mode only. When set HIGH, all ancillary
data packets are removed from both the Luma and Chroma channels of the input video
signal. The data contained in the packets are output at the corresponding pins. When set
LOW, all ancillary data packets remain in the video signal.
See Section 2-11.
15
MUX/DEMUX
I
Mode of operation. When set LOW, the GS1503 operates in Multiplex Mode.
When set HIGH, the GS1503 operates in Demultiplex Mode.

86, 88, 108,
113, 121,
129, 144
GND
-
Device ground.
17
ACLKA
I
Input audio signal clock at 6.144 MHz (128 fs) for channels 1 to 4.
19
ACLKB
I
Input audio signal clock at 6.144 MHz (128 fs) for channels 5 to 8.
21
ERROR
O
Format error indicator. When HIGH, the incoming video data stream contains TRS errors
or there are errors within the incoming ancillary data packets.
