Description
The CXD4016R is an IC that processes the transmitted digital signals used for infrared spatial digital audio communication (based on the IEC61603-8-1 standard) in consumer products. This IC contains the digital-to-analog converter (DAC) and a PLL circuit for RF signal. RF signal is processed by digital signal processing, so the operation is stable without any adjustments.
Features
♦ Performs all the transmitted digital signal processing on a single chip
♦ Supports the infrared spatial digital audio communication system formats for consumer uses
♦ Support the three audio sampling frequencies (32kHz, 44.1kHz, 48kHz)
♦ Direct output of RF signals enabled by on-chip DAC
♦ External RAM and PLL circuit not required
< Audio I/F Block >
♦ Interfaces for various audio ADCs
< Parity Generator Block >
♦ Automatic generation of Reed-Solomon parity for the infrared spatial digital audio communication system format
< Modulator Block >
♦ Digital processing throughout enables the transmitted RF signals in the infrared spatial digital audio communication system formats to be processed directly
♦ External analog circuit can be simplified by on-chip digital filter and on- chip DAC for RF signal applications
♦ Generation of subcarrier processed digitally
< Controller Block >
♦ Simple pin setting mode
♦ Serial interface provided by serial bus
< PLL Block >
♦ On-chip analog PLL circuit for generating the clock signals (640fs) required by the infrared spatial digital audio communication system formats -
