CXD2820R

Product Summary

The CXD2820R "DVB-T2" reception power
consumption is around 300 mW (typ.) in
ordinary reception environments and only
about 700 mW (typ.) during LDPC decoder
operating at maximum level.
The CXD2820R features high compatibility,
in both hardware and software, with the
current Sony "DVB-T/DVB-C" demodulator
LSI (the CXD2817R). Since both the
pin arrangement and the pin functions
are designed as extensions to those of the
CXD2817R, circuit board design and
modification are easy. Also, the register
functions and control specifications have high
compatibility with the CXD2817R, making it
possible to create a single driver that supports
both LSIs.

Features

1.Based on Sony research (as of February, 2010)
2.Second generation terrestrial digital broadcast standard. This is the improved version of the first generation "DVB-T".
Digital sound and video signals are transmitted using orthogonal frequency-division multiplexing (OFDM) digital modulation.
Using a time interleaver and LDPC code (a kind of error correction system) improves the transmission efficiency by approximately 50% compared with "DVB-T".
3.First generation terrestrial digital broadcast standard. This standard is adopted in various countries and regions around the world including Europe.
Digital sound and video signals are transmitted using orthogonal frequency-division multiplexing (OFDM) digital modulation.
4.Cable digital broadcast standard. This standard is adopted in various countries and regions around the world including Europe.
Digital sound and video signals are transmitted using quadrature amplitude modulation (QAM) digital modulation.
