Description
The GS1503B is a highly integrated, single chip solution for
embedding/extracting digital audio streams into and out of
high definition digital video signals. The GS1503B 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 GS1503B.
Each GS1503B 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 GS1503B’s can be cascaded for
insertion/extraction of up to 16 audio channels with no
external glue logic.
The GS1503B 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.
The GS1503B 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 GS1503B with Gennum’s GS1545 or
GS1522 for two chip HD SDI receive or transmit solutions.
The GS1503B operates from a single 3.3V power supply
with 5V tolerant I/O and is packaged in a 144 pin TQFP
package.
