SAA7740H規(guī)格書詳情
GENERAL DESCRIPTION
The SAA7740H is a function-specific digital signal processor. The device is capable of performing processing for listening-environments such as equalization, hall-effects, reverberation, surround-sound and digital volume/balance control. The SAA7740H can also be reconfigured (in a dual and quad filter mode) so that it can be used as a digital filter with programmable characteristics.
FEATURES
Hardware
? Two digital inputs and two digital outputs in the I2S-bus format (i.e. 4 audio channels)
? Independent input/output interfaces
? Slave input/output interfaces
? Slave processing
? I2C-bus microcontroller interface
? DC filtering at the inputs
? One programmable 2nd-order digital filter unit
? Two multiply accumulate processor units (24 × 16-bit/MAC)
? DRAM interface and address computation unit for external delay lines
? On-chip coefficient and external delay line address storage
? Hardware controlled soft mute via the MUTE pin
? Hardware controlled soft demute via the RST pin
? Operating ambient temperature; ?40 to +85 °C.
Software
? 5-band parametric equalizer with selectable centre frequency, slope setting and boost/cut gain settings from ?12 to +12 dB
? Stereo width control from mono to stereo to spatial stereo
? Stereo Hall-effects for field acoustics, such as concert halls, with 8 coefficients and 8 delayed taps per channel
? External delay line processing for delays up to 1 second
? Reverberation with selectable reverberation time (up to 5 seconds) and energy
? Three different surround sound programs to obtain a spatial effect on 4 loudspeakers
? Passive DOLBY surround processing with the addition of an external dynamic noise reduction IC
? Karaoke processing
? Dual 16th-order correction filtering
? Quad 8th-order correction filtering
? Digital volume and balance control
? Soft controlled soft mute/demute via the microcontroller interface
? Input switching matrix
? Output rear and front switching matrix.
APPLICATIONS
? Digital amplifiers
? Audio combination sets
