SAA7705H Product details

GENERAL DESCRIPTION
The SAA7705H performs all the signal functions in front of the power amplifiers and behind the AM and FM multiplex demodulation of a car radio or the tape input. These functions are:
• Interference absorption
• Stereo decoding
• RDS decoding
• FM and AM weak signal processing (soft mute, sliding stereo, etc.)
• Dolby-B tape noise reduction
• Audio controls (volume, balance, fader and tone).

FEATURES
Hardware
• Three 3rd-order Switched Capacitor Analog-to-Digital converters (SCADs)
• Digital-to-Analog Converters (DACs) with four times oversampling and noise shaping
• Digital stereo decoder for the FM multiplex signal
• Improved digital Interference Absorption Circuit (IAC) for FM
• Radio Data System (RDS) processing with an optional 16-bit buffer via a separate channel (two tuners possible)
• Auxiliary high Common-Mode Rejection Ratio (CMRR) analog CD input (CD-walkman, speech, economic CD-changer, etc.)
• I2C-bus controlled
• Four channel 5-band I2C-bus controlled parametric equalizer
• Two separate full I2S-bus and LSB-justified formats high performance input interfaces
• Audio output short-circuit protected
• Separate AM left and right inputs
• Phase-Locked Loop (PLL) to generate the high frequency DSP clock from a common fundamental oscillator crystal
• Analog single-ended tape inputs
• I2S-bus subwoofer output (mono or stereo)
• Expandable with additional DSPs for sophisticated features through an I2S-bus gateway
• Operating ambient temperature from −40 to +85 °C.

Software
• Improved FM weak signal processing
• Integrated 19 kHz MPX filter and de-emphasis
• Electronic adjustments: FM/AM level, FM channel separation and Dolby level
• Baseband audio processing (treble, bass, balance, fader and volume)
• Dynamic loudness or bass boost
• Audio level meter
• Tape equalisation (tape analog playback)
• Music Search System (MSS) detection for tape
• Dolby-B tape noise reduction
• Adjustable dynamics compressor
• CD de-emphasis processing
• Improved AM reception
• Soft audio mute
• AM IAC
• Pause detection for RDS updates
• Signal level, noise and multipath detection for AM/FM signal quality information.

APPLICATIONS
• Car radio systems
