GS1503

HD EMBEDDED AUDIO CODEC

DATA SHEET

FEATURES

DESCRIPTION

• complies with SMPTE 292M and SMPTE 299M

• single chip HD embedded audio solution

The GS1503 is a highly integrated, single chip solution for

embedding/extracting digital audio streams into and out of

high definition digital video signals. The GS1503 supports

insertion/extraction of 24-bit synchronous audio data with a

48kHz sample rate. Audio signals with different sample

rates may be converted to 48kHz by using audio sample

rate converters before or after the GS1503.

• operates as an embedded audio multiplexer or

demultiplexer

• full support for 48kHz synchronous 24-bit audio

• support for 8 channels of audio per device

• cascadable architecture supports up to 16 audio channels

• integrated scrambler/descrambler and word alignment

• CRC error detection and insertion

Each GS1503 supports all processing required for

embedding/extracting up to eight digital audio channels in

the horizontal ancillary data space of the video chroma

channel. Two GS1503’s can be cascaded for insertion/

extraction of up to 16 audio channels with no external glue

logic.

• audio control packet insertion and extraction

• arbitrary data packet insertion and extraction

• 3.3V power supply with 5V tolerant I/O

The GS1503 supports embedding/extracting of audio

control and arbitrary data packets in the horizontal ancillary

data space of the video luma channel. It also supports line

CRC detection and insertion.

• 144 pin LQFP package

APPLICATIONS

HD SDI Embedded Audio

The GS1503 supports HD video standards at 74.25MHz

and 74.25/1.001MHz rates. It has an on chip SMPTE

compliant scrambler/de-scrambler, and integrated word

alignment. Use the GS1503 with Gennum’s GS1545 or

GS1522 for two chip HD SDI receive or transmit solutions.
