M88RS2000  -  Single-chip DVB-S Receiver

The M88RS2000 is a highly integrated single-chip receiver used for reception of DVB-S digital satellite TV signals. The device combines the functions of a tuner, a demodulator and an LNB controller on a single chip, thus providing a fast, easy and cost-effective solution for digital satellite front-ends.

The M88RS2000 receives an RF input, down-converts it to baseband signal, digitally demodulates it, corrects errors generated during data transmission, and finally outputs MPEG transport stream.

The M88RS2000 is flexible and able to support input frequency of 950 MHz to 2150 MHz and symbol rate of 1 Msps to 45 Msps. The device is fully configurable via a serial 2-wire bus. The device works properly with a voltage ranging from 2.5 V to 3.3 V.
