CXD4017R
Reception Digital Signal Processor IC for Infrared Spatial Digital Audio Communication
Description
The CXD4017R is an IC that processes the
received digital signals used for infrared spatial digital
audio communication (based on the IEC61603-8-1
standard) in consumer products. This IC contains the
analog-to-digital converter (ADC) for RF signal
applications and a PLL circuit for audio applications.
64 pin LQFP (Plastic)
Features
• Performs all the received digital signal processing
on a single chip.
• Supports the infrared spatial digital audio
communication system formats for consumer
uses.
• Direct input of RF signals enabled by on-chip
ADC.
• External RAM and PLL circuit not required.
Demodulator Block
• Digital processing throughout enables the received
RF signals in the infrared spatial digital audio
communication system formats to be processed
directly.
• External analog circuit can be simplified by digital
filter and on-chip ADC for RF signal applications.
• Reproduction of subcarrier processed digitally.
Error Corrector Block
• Enables error correction for infrared spatial digital
audio communication system formats.
Output Interface Block
• Digital-to-analog converter (DAC) for various audio
applications can be connected directly.
Controller Block
• Simple pin setting mode
• Serial interface provided by serial bus
• Enables output of error correction state.
PLL Block
• On-chip PLL circuit for reproducing the clock
signals required by the infrared spatial digital
audio communication system formats.
