INTEGRATED CIRCUITS DATA SHEET SAA2505H Digital multi-channel audio IC (DUET) Preliminary specification File under Integrated Circuits, IC01 1998 Mar 10 Philips Semiconductors Preliminary specification Digital multi-channel audio IC (DUET) FEATURES Hardware features · Two 40 MIPS 20-bit DSP cores · All input and output buffer RAM is on-chip · Program ROM on-chip for all decoding modes · Two I2S-bus inputs with normal, double and quad speed mode (slave only) · Second serial input usable for ADC (Karaoke input) · Three normal and double speed I2S-bus outputs (slave and master from 256 and 384fs) · One normal, double, quad speed I2S-bus output (slave and master from 256 and 384fs) · Japanese EIAJ serial input and output formats · Sony Philips Digital Interface (SPDIF) output · I2C-bus control (up to 400 kHz) · 3.3 V supply with 5 V TTL compatible inputs/outputs · Boundary scan for printed-circuit board testing. Software features · AC-3 up to 5.1 channels · MPEG 2 L2 up to 7.1 channels · MPEG 1 L2 (Video-CD) 2 channels at 44.1 kHz · Dolby pro-logic decoding at 32, 44.1 and 48 kHz · Output configuration for 7, 5, 4, 3, 2 and 1 channels with or without Low Frequency Enhancement (LFE) · Bass redirection for small satellite loudspeakers plus subwoofer · Karaoke voice mix · Dynamic range compression (AC-3 and MPEG) · Adjustable delay up to 15 ms for surround channels (1.5 kbyte words) · Adjustable delay up to 5 ms for centre channel (250 words) · Rounding to DAC word length · Mute by pin and I2C-bus command · AC-3 and MPEG bitstream information available via the I2C-bus · Concealment of CRC errors · SPDIF coded output · Fully programmable SPDIF channel status information. APPLICATIONS SAA2505H The SAA2505H is intended for all markets where a multi-channel audio decoder for Dolby AC-3 and MPEG 2 is required. Primary markets are for DVD video players, TV sets and audio/video amplifiers. GENERAL The SAA2505H decodes multi-channel audio up to MPEG 7.1, AC-3 5.1 and pro-logic on a dual DSP core. The device contains all of the RAM and ROM necessary for operation. This minimises the need for external components and no microcode download is required. The device is primarily intended for audio/video surround sound amplifiers where the amplifier is connected to the data source by means of SPDIF (IEC 60958). The input interface is, therefore, made for SPDIF (IEC 60958) and formatted for the I2S-bus. The primary device output is PCM, sent via four I2S-bus ports. There is also a SPDIF (IEC 60958) formatted output. User control is achieved via an I2C-bus. However, the SAA2505H is capable of stand-alone operation. 1998 Mar 10 2 Philips Semiconductors Preliminary specification Digital multi-channel audio IC (DUET) QUICK REFERENCE DATA SYMBOL VDDD IDDD VDDA IDDA fxtal Tamb VESD PARAMETER digital supply voltage digital supply current analog supply voltage analog supply current crystal frequency operating ambient temperature electrostatic discharge sensitivity f
