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 two-
wire 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 front-
end phase noise.
