1 FEATURES
1.1 Hardware features
• Digital Signal Processor (DSP) core:
– 18 bits data width, 12 bits coefficient width
– Separate X, Y and P memories (both 384 bytes word
XRAM and YRAM, 3 kbytes word PROM)
– 1 kbytes delay line memory suited for Dolby Pro
Logic Surround.
• Inputs:
– 2 slave 18-bit digital stereo inputs: I2S-bus and
LSB-justified serial formats
– 2 master 18-bit digital stereo inputs: I2S-bus and
LSB-justified serial formats.
• Outputs:
– 4 DACs with 4-times oversampling and noise
shaping, fed to 4 output pins and configurable from
the DSP program, as left, right, front and surround
channels of a Dolby Pro Logic Surround system
– 2 master 18-bit digital stereo outputs: I2S-bus and
LSB-justified serial formats.
• 4-channel 5-band or 2-channel 10-band
I2C-bus controlled parametric equalizer
• I2C-bus microcontroller interface for:
– Access to full X and Y memory space
– Control of hardware settings: selectors,
programmable clock generations, etc.
• Controllable Phase-Locked Loop (PLL) to generate the
high frequency DSP clock from common fundamental
oscillator crystal
• 3.3 V process with 3.3 or 5 V digital periphery:
– 3.3 or 5 V I2S-bus and I2C-bus microcontroller
interfacing.
• Operating temperature range from 0 to 70 °C.
1.2 Software features
• Dolby Pro Logic Surround/Dolby 3 stereo:
Trademark of Dolby Laboratories Licensing Corporation
• Noise generation: A pink noise generator is included
for installation of the Dolby Pro Logic/Dolby 3 stereo
mode
• Hall/Matrix Surround: When no Dolby Pro Logic
Surround source material is available then this mode
can be used to produce a signal in the surround channel
• Incredible Surround (222-IS): This algorithm expands
the stereo width (stereo expander). This is intended to
be used when the 2 speakers are placed close together
(TV set and Midi set).
• Robust Incredible Surround (222-RIS): Same as
incredible surround only an alternative algorithm
• 3D Surround (422) or Incredible Virtual Surround:
Dolby Pro Logic Surround reproduced by 2 speakers
(L and R)
• IS-3D Surround (422-IS): Same as 3D Surround (422)
only with extra stereo width expander on left and right
• RIS-3D Surround (422-RIS): Same as IS-3D Surround
(422) with alternative algorithm
• 3D Surround (423) or Incredible Virtual Surround:
Dolby Pro Logic Surround reproduced by 3 speakers
(L, C and R)
• IS-3D Surround (423-IS): Same as 3D Surround (423)
only with extra stereo width expander on left and right
• RIS-3D Surround (423-RIS): Same as IS-3D Surround
(423-IS) with alternative algorithm
