Intel Corporation

Overview

The CE6313 is a QPSK/BPSK 1 - 45 MSps demodulator and channel decoder for digital satellite television

transmissions compliant to both DVB-S and DSS standards and other systems, such as LMDS, that use the same

architecture.

A Command Driven Control (CDC) system is provided making the CE6313 very simple to program. After the tuner

has been programmed to the required frequency to acquire a DVB transmission, the CE6313 requires a minimum

of five registers to be written.

The CE6313 provides a monitor of bit error rate after the QPSK module and also after the Viterbi module. For

receiver installation, a high speed scan or 'blind search' mode is available. This allows all signals from a given

satellite to be evaluated for frequency, symbol rate and convolutional coding scheme. The phase of the IQ signals

can be automatically determined.

Full DiSEqC is provided for both writing and reading DiSEqC messages. Storage in registers for up to eight data

bytes sent and eight data bytes received is provided.
