Transmission Digital Signal Processor IC for Infrared Spatial Digital Audio Communication
CXD4016R
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 >
Š Interfaces for various audio ADCs
< Parity Generator Block >
Š Automatic generation of Reed-Solomon parity for the infrared spatial digital audio communication
system format
< Modulator Block >
Š Digital processing throughout enables the transmitted RF signals in the infrared spatial digital audio
communication system formats to be processed directly
Š External analog circuit can be simplified by on-chip digital filter and on-chip DAC for RF signal
applications
Š Generation of subcarrier processed digitally
< Controller Block >
Š Simple pin setting mode
Š Serial interface provided by serial bus
< PLL Block >
Š On-chip analog PLL circuit for generating the clock signals (640fs) required by the infrared spatial digital
audio communication system formats
