ADAMB

Advanced Digital Audio Multi channel decode processor

Outline

The YSS944 (ADAMB-f)/YSS943 (ADAMB-b)/YSS940 (ADAMB-nd) is an audio decoding digital signal

processor that integrates onto a single chip the various digital signal processing functions required for AV

amplifiers, etc. It includes an advanced 32-bit floating-point DSP and is able to decode a variety of audio

formats.

[Note]

• The contents described in this manual are implemented by downloading boot firmware.

For detailed information about the boot firmware, please contact YAMAHA.

• The YSS943 cannot execute DTS-ES and DTS Neo:6 decoding.

• The YSS940 cannot execute any decoding related to DTS (DTS, DTS-ES, DTS 96/24, and DTS Neo:6).

Features

•

Supports various types of decoding up to 7.1 channels (5.1/6.1/7.1 channels selectable).

5.1-channel decoding of Dolby Digital (AC-3), DTS, AAC.

6.1-channel decoding of Dolby Digital EX, DTS-ES.

DTS 96/24 decoding and audio interface clock division/switching functions.

Dolby Pro Logic IIx and DTS Neo:6 decoding

Tone control and bass management functions

Function modification/expansion by downloading firmware to on-chip memory

Lip-sync function that enables synchronization of voice and video with variable voice delay

Supports sampling frequencies up to 192 kHz during PCM playback.

1/2 down sampling function when two PCM channels are played back

Dolby Digital/DTS/AAC decode information output function (can be read by microprocessor)

High-speed/high-accuracy operation by 32-bit floating-point DSP

Operating frequency: 180 MHz (178.176 MHz)

Data bus width: 32 bits (24-bit mantissa and 8-bit exponent)

Multiplier/adder: 32 bits × 32 bits + 55 bits → 55 bits (47-bit mantissa and 8-bit exponent)

No external memory needed (external memory is used when delay is increased.)

Eight general I/O ports

On-chip PLL for generation of high-speed internal operating clock

Supply voltage: 1.2 V (core block) and 3.3 V (pin block)

Low power consumption: about 210 mW (standard value during Dolby Digital decoding)

Si-gate CMOS process

Lead-free plating LQFP144 package (YSS944-VZ, YSS943-VZ, and YSS940-VZ)
