CONFIDENTIAL ADVANCE INFORMATION
Crescendo II+ SoundBar SoC
Product Brief
Analog Reinvented
The Crescendo II+ SoundBar is a 3rd-generation SoC that integrates all soundbar audio functions in a 128pin Low Profile Quad Flat Pack (LQFP) package.
For best sound, the Crescendo II+ SoC is built on the ESS SABRE DAC technology normally found only in
high-end audiophile and professional audio equipments to deliver spectacular music with an unsurpassed
sound stage, utilizing the ESS patented HyperStream modulator capable of 100% modulation and
unconditional stability to drive analog or digital amplifiers.
For lowest system BOM, the Crescendo II+ SoC adopts a unified memory architecture for lowest memory
cost. It integrates a 32-bit RISC and a 64-bit media processor for audio decoding, post-processing, lipsynchronization and sound effects such as virtual surround and bass enhancement, a hardware parametric
equalizer (PEQ) for speaker equalization, an automatic gain limiter (AGL) for anti-clipping control, a userprogrammable 32-bit Audio Coprocessor for custom sound algorithms, a 5.1-channel patented
HyperStream Class D or D/A converter for driving digital or analog power stages, a 3-input HyperStream
stereo ADC for connection to line input sources, a 4-input SPDIF/ARC receiver for connection to coaxial,
optical, HDMI and ARC input sources, an 8-channel I2S input for connection to HDMI repeater, and a fullspeed USB host controller for firmware upgrade or music playback from thumb drives or iPod.
