CXD2820R Circuit Board Chips DBS Audio Signal Processor




The CXD2820R are audio signal processors designed for DBS applications.

These LSIs perform all digital processing from QPSK demodulation to analog audio output on a single chip.




QPSK and PCM demodulators and DAC output are configured on a single chip.

Descrambler interface according to the COATEC system and SkyPort system




QPSK demodulator

• Carrier, clock and data regeneration

• ALC and VCXO adjustment-free


PCM demodulator

• Frame sync protection by correlation detection

• De-interleaving and descrambling

• BCH error correction, range bit error correction

• Audio data range control Expansion from 10 to 14 bits in A mode Upper bit majority correction in B mode • Control sign integration correction, chargeable flag integration correction by master frame synchronization

• Interface output for external DAC

• Digital interface output 1-bit DAC output

• Quadruple oversampling filter

• Digital de-emphasis circuit

• 1-bit stereo


DAC with 2nd-order ∆∑ format noise shaper S/N ratio : 90dB (Typ.)

Distortion : 0.011% (Typ.)


CPU interface

• I2C bus Descrambler interface

• COATEC system,


SkyPort system Mute functions

• Error occurrence frequency detection mute

• Audio chargeable flag detection mute

• Control sign (B7) detection mute



Silicon gate CMOS IC



TVs, VCRs with built-in BS tuners
