BCM4201 - Universal Satellite Receiver

Universal Satellite Receiver

The BCM4201 is a very flexible, cost-effective solution. It is compatable with DVB, DIRECTV and Digicipher II ITU-R 217/11 standards, enabling manufacturers to design the BCM4201 into a single-standard Integrated Receiver Decoder IRD or a multi-standard IRD. The receiver supports variable bit rates up to 85 Mbps, which allows it to adapt to various satellite transponders in Europe, North America, and Asia. The BCM4201 is capable of supporting low rate applications, down to 1 MBaud, for applications such as SCPC. The BCM4201 is optimized for high-volume manufacturing. This level of integration in the BCM4201 significantly reduces the cost and complexity of manufacturing IRDs.

The BCM4201 Universal Satellite Receiver is an integrated digital transmission solution for satellite Integrated Receiver Decoders (IRDs). Integrated features in the BCM4201 include a 2 - 85 Mbps variable rate BPSK/QPSK/OQPSK receiver, dual 8-bit A/D converters, a phase/frequency recovery block, variable rate digital filters, square-root Nyquist matched filters, acquisition and tracking loops, and a DVB/DIRECTV/Digicipher II compliant concatenated Viterbi/Reed-Solomon FEC decoder with deinterleaver. The receiver accepts an analog baseband or IF modulated (up to 480 MHz) signal, and transmits a demodulated error corrected output data stream. The BCM4201 supports the DVB digital transmission standard for satellite broadcasting, that is in worldwide use today, the DIRECTV digital transmission standard and Digicipher II ITU-R 217/11 digital transmission standard.
