Overview

AVL6211 DVB-S2/DVB-S Channel Receiver Data Sheet Description The AVL6211 is an enhanced version of the AVL2108 device.
The AVL6211 is a highly integrated DVB-S2 and DVB-S channel receiver IC.
It converts a baseband analog IQ signal from a satellite tuner and performs a set of sophisticated demodulating and decoding operations to output an MPEG video/audio stream.
The AVL6211 provides simple and flexible control via a standard two-wire bus.
A simplified block diagram of the device is shown in Figure 1-1.
The AVL6211 includes dual, differential, high performance, analog to digital converters (ADC) with a built-in compensation circuit for DC offset and IQ imbalance.
An RF AGC output is provided for simple gain control of the satellite tuner via an RC network.
After passing a timing recovery loop and frequency recovery loop, the signal samples are further processed by an equalizer to output decision bits to an FEC decoder.
The decoded bits are finally packetized in the MPEG interface block.
The configuration of the AVL6211 is easily performed through a set of registers via a standard two-wire bus.
To simplify the interface to the host system, this same twowire bus is used to communicate with the separate tuner two-wire bus and the DiSEqC™ interface to the LNB.
The AVL6211 can achieve fast acquisition at frequency offsets up to 5 MHz and maintains synchronization under the most severe frontend phase noise.
