Direct Broadcast Satellite (DBS) has been one of the most successful new product

introductions in the history of consumer electronics. This product represents the first

application of digital video compression for broadcast television. Originally intended to

provide cable quality television services to remote areas, this product is now offering a

competitive replacement to cable services in many urban areas.

The first operational systems employ closed proprietary signaling structures. The

European Broadcasting Union (EBU) has developed the first open standard (DVB-S) for

DBS services. The broadcasting community has embraced this standard which is now

being adopted for new systems throughout the world. This widely accepted open

standard is essential for DBS to achieve full market potential.

The HDM8513A

TM is a fully DVB-S&DSS compliant ADC/QPSK demodulator/FEC

device which provides an MPEG-2 stream to be processed by the conditional access

and video decompression circuits. The demodulator clocked with a fixed frequency is

true variable rate over the range of 1 to 55M symbols-per-second. This product

achieves the highest performance and flexibility. It minimizes the cost of external

circuits, thus reducing overall system cost.
