CS49DV8C Data Sheet
32-bit Dual Audio DSP Engine
featuring Multichannel Dolby Volume
FEATURES
32-bit Post-Processor Audio DSP supports Multichannel
Dolby Volume
Programmable through DSP Composer
CS49DV8, supports up to 7.1 Channels of Dolby Volume
processing at 48 kHz, 44.1 kHz or 32 kHz.
— Input Configurable for all input/output digital audio types
(I2S, LJ/RJ, and TDM)
— 32-bit data path delivers uncompromised dynamic range
— 192 kHz capable integrated S/PDIF transmitter
— DAO can operate in master or slave mode (SCLK &
LRCLK)
Integrated Clock Manager/PLL
— Capable of operating from a wide variety of external
crystals or external oscillators
Input Fs Auto Detection, Reporting and Handling
Sample rate conversion.
Master & Slave Host Boot Capability via Serial Interface
SPI interface capable of running up to 25 MHz during run
time
1.8V Core and a 3.3V I/O that is tolerant to 5V input
The new CS49DV8C is the fastest time-to-market, mass-
production ready Multichannel Dolby Volume solution available.
The target applications for the CS49DV8C DSP are:
— Soundbars
— DTVs with Integrated Soundbars
— HDTV Stands/Furniture with Integrated Soundbars
— Automotive Head Units
— Automotive Outboard Amplifiers
— Blu-ray Disc & DVD Receivers / HTiBs
All of these applications and many more that use volume control
and are subject to playback from sources that do not have consis-
tent volume levels will benefit from the CS49DV8C Dolby Volume
solution.
