M88RS6000 - Single-chip DVB-S2/S Receiver

The M88RS6000 is a highly integrated single-chip DVB-S2/S receiver consisting of a tuner, a DVB-S2/S demodulator and an LNB controller. The device is fully compliant with the DVB-S2 and DVB-S standards and supports QPSK, 8PSK, 16APSK and 32APSK demodulation schemes.

The M88RS6000 receives RF signals in range of 950 MHz to 2150 MHz, down-converts the signals to baseband, digitally demodulates them, and finally outputs an MPEG transport stream.

The M88RS6000 supports symbol rate up to 53Msps, channel bit rate up to 130Mbps and code rate from 1/4 to 9/10. All key features are included in the robust integrated digital signal processor (DSP), like the blind scan, fade detection, timing and carrier recovery, performance monitoring, co-channel interference cancellation, command interface and DiSEqC™ 2.X interface, etc.

The device is controlled via a serial 2-wire bus interface. It works with low power consumption.
