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.

HDMIULC6-4SC6 General Description

The HDMIULC6-4SC6 is a monolithic, application specific discrete device dedicated to ESD protection of the HDMI connection. It also offers the same high level of protection for IEEE 1394a and IEEE 1394b/c, USB 2.0, Ethernet links, and video lines. Its ultra high cutoff frequency (5.3 GHz) secures a high level of signal integrity.

The device topology provides this integrity without compromising the complete protection of ICs against the most stringent ESD strikes.

HDMIULC6-4SC6 Features

4 line 15 kV ESD protection
Protects VBUS when applicable
Ultra high bandwidth - no inluence on signal rise and fall times - maximised number of signal harmonics
Very low leakage current: 0.5 µA max.
Fast response time compared with varistors
SOT23-6L package
RoHS compliant

HDMIULC6-4SC6 Typical Application

HDMI ports at 1.65 Gb/s and up to 3.2 Gb/s
IEEE 1394a, b, or c up to 3.2 Gb/s
USB 2.0 ports up to 480 Mb/s (Hi-Speed)
Ethernet port: 10/100/1000 Mb/s
Video line protection
