CONFIDENTIAL ADVANCE INFORMATION
Analog Reinvented
Crescendo II SoundBar SoC
Product Brief
The Crescendo II SoundBar is an SoC targeted for TV soundbar applications.
To enable the lowest system BOM cost, the Crescendo II SoundBar employs a unified memory
architecture and integrates all TV soundbar processing functions in a 128-pin Low Profile Quad Flat
Pack (LQFP) package.
The Crescendo II SoundBar’s core A/V decoder is built on the ESS proprietary dual CPU
Programmable Multimedia Processor (PMP) core consisting of 32-bit RISC and 64-bit Media
Processor that deliver the best soundbar feature set. In addition, the Crescendo II SoundBar
integrates an audio postprocessing DSP for sound effect processing such as virtual surround or
stereo expansion.
The Crescendo II SoundBar integrates a hardware parametric equalizer for speaker equalization, a
5.1ch Hyperstream™ PWM or D/A converters to deliver the best sound via digital or analog power
amplifiers, a 2-input SPDIF receiver, a 3-input audio ADC for connection to line-in sources an 8channel I2S input for connection to HDMI repeater or Blu-ray processor, remote and GPIO
handlers for buttons and LEDs, and a FS USB 2.0 host controller for firmware upgrade at the field
or music playback from thumb drives or iPod.
