HDM8515 General Description

The HDM8515 digital demodulator for direct broadcast satellite receivers is a single chip solution fully compliant with the European Telecommunications Standards Institute (ETSI) specification ETS 300 421. This chip integrates an A/D converter, a variable rate matched filter, a variable rate QPSK demodulator with a Viterbi decoder, a deinterleaver and a Reed Solomon decoder.

The HDM8515, which is implemented in a 0.25 micron CMOS, Four Layer Metal Process, provides variable rate capability while operating with a fixed frequency sampling clock. Digital samples of baseband I and Q data are generated by an internal A/D converter, then provided to the demodulator at a fixed sample rate. The root raised cosine filter is implemented internally with fully digital techniques.

Similarly, the symbol timing recovery and carrier phase tracking functions are performed entirely in the digital domain. This approach provides minimum constraints on external circ uits, thus reducing overall system costs.

The HDM8515 may be configured by an external processor for a specific symbol rate, and carrier frequency along with loop gain parameters. The HDM8515 provides an external AGC signal which is used to control the gain of the analog signal which is applied to the down-converters. And it also provides a digital AGC internally which controls the gain of the signal out of the matched filters. In addition, the HDM8515 provides fully programmable sweep circuitry to aid in initial acquisition when large frequency offsets may be present.

The digital frequency translation capability of the HDM8515 permits this part to be used in frequency multiplexing applications. In this application, an entire transponder bandwidth containing many signals is sampled at a fixed rate. The digital oscillator within the HDM8515 is programmed to the specific desired carrier frequency within that band to permit the selected signal to be passed through the baseband filter and processed by the demodulator circuits.
