Description
The S94324171 is an electronic component model belonging to the product category of IC Chips. It is an audio decoding digital signal processor that integrates various digital signal processing functions required for AV amplifiers, etc., onto a single chip. With an advanced 32-bit floating-point DSP, it can decode a variety of audio formats.
Specifications and 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 (S943-VZ).
Application Scenarios
- AV amplifiers for home theaters.
- Car audio systems.
