Digital Signal Processor
Preliminary specification
SAA7715AH
1 FEATURES
1.1 Hardware
24-bit Philips 70 MIPS DSP core (24-bit data path and
12/24-bit coefficient path)
1.5 kbyte of downloadable DSP program memory
(PRAM)
2 kbyte of DSP program memory (PROM)
2.875 kbyte of re-programmable DSP data memory
(XRAM)
1.5 kbyte of re-programmable DSP coefficient memory
(YRAM)
Four stereo digital serial inputs (8 channels) with
common BCK and WS. To these inputs the I2S-bus
format or LSB-justified formats can be applied
One stereo bitstream DAC (2 channels) with 64 fold
oversampling and noise shaping
Selectable clock output (pin SYSCLK) for external slave
devices (128fs to 512fs)
Four stereo digital serial outputs (8 channels) with
selectable I2S-bus or LSB-justified format
Two SPDIF inputs combined with digital serial input
On-board WS_PLL generates clock for on-board DAC
and output pin SYSCLK
I2C-bus controlled (including fast mode)
Programmable Phase-Locked Loop (PLL) derives the
clock for the DSP from the CLK_IN input
• −40 to +85 °C operating temperature range
Supply voltage only 3.3 V
All digital inputs are tolerant for 5 V input levels
Power-down mode for low current consumption in
standby mode
Optimized pinning for applications with other Philips
DACs (such as UDA1334, UDA1355 and UDA1328).
1.2 Possible firmware
Dolby®(1) Pro Logic decoding
Smoothed volume control (without zipper noise)
Automatic Volume Levelling (AVL)
Dynamic bass enhancement
Ultra bass
(1) Dolby — Available only to licensees of Dolby Laboratories
Licensing Corporation, San Francisco, CA94111, USA, from
whom licensing and application information must be obtained.
Dolby is a registered trade-mark of Dolby Laboratories
Licensing Corporation.
Incredible surround
Incredible mono (Imono)
DPL virtualizer
Dolby digital virtualizer (DVD post-processing)
Dynamic compressor
Spectral enhancer
Equalizer with peaking/shelving filters
DC filters
Bass/treble control
Dynamic loudness
Tone/noise generator
Graphical spectrum analyser
Configurable Delay Unit (DLU)
Sound steering/elevation for car applications
Sample Rate Conversion (SRC).
2 APPLICATIONS
As co-processor for a car radio DSP in a car radio
application for additional acoustic enhancements
(sound steering/sound elevation/signal processing)
Multichannel audio: in DVD and Home theatre
applications as post-processing device such as signal
virtualization (virtual 3D surround) and acoustic
enhancement, tone control, volume control and
equalizers
Multichannel decoding: Dolby Pro Logic and virtual
3D surround
PC/USB audio applications: stereo widening (Incredible
surround), sound steering, sound positioning and
speaker equalization.
