CXD4017R

CXD4017R 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. 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. 64 pin LQFP (Plastic) www.DataSheet4U.com Reception Digital Signal ...
