Two decoders in one for double the set-top box

Philips Semiconductors says it has developed the world's first IC to embed two DVB-S/DSS channel decoders.

Philips Semiconductors says it has developed the world's first IC to embed two DVB-S/DSS channel decoders.

The highly integrated TDA10093HT solution offers satellite broadcasters and set-top box and TV manufacturers significant system cost reductions, when compared with two conventional channel receivers.

Targeted at next-generation satellite set-top boxes, the chip will enable a new class of feature-rich broadcast applications to be offered to consumers.

Already the leading supplier of competitive solutions for satellite set-top boxes, Philips Semiconductors' latest announcement promises to speed the widespread adoption of advanced functions via the satellite set-top box.

Applications for the TDA10093HT chip include DVB-S and DSS receivers, time-shifting boxes with receivers' functionalities and next-generation set-top boxes, featuring PIP (picture in picture), watch and record and PVR functionality.

Based on the TDA10085HT, the TDA10093HT, housed in a small TQFP100, is a single-chip dual QPSK channel receiver for satellite television reception that matches both DSS and DVB-S standards.

Each channel is fully independent and can be programmed via the I2C bus.

The device contains 8bit Flash analogue-to-digital convertors, a variable rate BPSK/QPSK coherent demodulator and forward error correction functions per channel.

The transport stream is available in parallel mode for the two channels, but also simultaneously in serial, for one of the selected channels.
