AC3D3
96kHz DIR + Dolby Digital / Pro Logic / DTS decoder + Sub DSP
OUTLINE
YSS922 is one chip LSI consisting of three built-in blocks : Dolby Digital (AC-3) / Pro Logic & DTS decoder
(Main DSP), a programmable sound processing DSP (Sub DSP) and SPDIF receiver (DIR) which can handle up to
96kHz sampling frequency.
The Sub DSP is capable of realizing various sound fields, such as virtual surround by
down-loading the program and coefficient from outside.
FEATURES
DIR Block
Sampling frequency: two ranges are available including;
32k to 48kHz (normal rate) and
64k to 96kHz (double rate)
Provides master clock, 256fs, to DAC, ADC and other peripheral devices. The clock output can be controlled
with various modes determined by register setting.
Has a pin that indicates the double rate operation.
Every channel status and user data can be read through the microprocessor interface.
Has an output pin for interrupt that is activated by changing of the status information.
Internal operation frequency: 25MHz
Main DSP Block
Dolby Digital (AC-3) / Pro Logic and DTS decode
High quality internal 24 bit DSP
No external memory is required. (Memory for center and surround channel delay is included.)
AC-3 Karaoke mode.
Supports compression modes at AC-3 / DTS decoding.
Pro Logic decoding for Dolby Digital 2 channels decoded signal as well as ordinary PCM signal.
Reads Dolby Digital / DTS decode information through the microprocessor interface.
Included de-emphasis filter for the PCM signal.
Internal operation frequency: 30MHz
