CONFIDENTIAL ADVANCE INFORMATION
Ensemble II SoC
Product Brief
Analog Reinvented
The Ensemble II SoC is targeted for BD home theater and TV soundbar applications.
To enable the lowest system BOM cost, the Ensemble II SoC employs a unified memory
architecture and integrates all BD home theater and TV soundbar processing functions in a 128-pin
Low Profile Quad Flat Pack (LQFP) package.
The Ensemble II SoC’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 home theater and soundbar feature set. In addition, the Ensemble II SoC integrates an
audio postprocessing DSP for sound effect processing such as virtual surround or stereo
expansion.
The Ensemble II SoC integrates a hardware parametric equalizer for speaker equalization, a 7.1ch
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, a stereo
MIC ADC for connection to microphones, an 8-channel 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.
