FEATURES Fully programmable 28-bit audio processor for enhanced ATV sound—default audio processing flow loaded on reset Implements Analog Devices, Inc. and third-party branded audio algorithms Adjustable digital delay line for audio/video Synchronization for up to 200 ms stereo delay High performance 24-bit ADC and DAC 94 dB DNR performance on DAC channels 95 dB DNR performance on ADC channels Headphone output with integrated amplifiers High performance pulse-width modulation (PWM) digital outputs Multichannel digital baseband I/O 4 stereo synchronous digital I2S input channels One 6-channel sample rate converter (SRC) and one stereo SRC supporting input sample rates from 5 kHz to 50 kHz One stereo synchronous digital I2S output S/PDIF output with S/PDIF input mux capability Fast I2C control Operates from 3.3 V (analog), 1.8 V (digital core), and 3.3 V (digital interface) Available in 80-lead LQFP APPLICATIONS General-purpose consumer audio post processing Home audio DVD recorders Home theater in a box systems and DVD receivers Audio processing subsystems for DTV-ready TVs Analog broadcast capability for iDTVs GENERAL DESCRIPTION The ADAV4601 is an enhanced audio processor targeting advanced TV applications with full support for digital and analog baseband audio. The audio processor, by default, loads a dedicated TV audio flow that incorporates full matrix switching (any input to any output), automatic volume control that compensates for volume changes during advertisements or when switching channels, dynamic bass, a multiband equalizer, and up to 200 ms of stereo delay memory for audio-video synchronization. Alternatively, Analog Devices offers an award-winning graphical programming tool (SigmaStudio™) that allows custom flows to be quickly developed and evaluated. This allows the creation of customer-specific audio flows, including the use of ADI library of third-party algorithms. The analog I/O integrates Analog Devices proprietary continuous- time, multibit Σ-Δ architecture to bring a higher level of performance to ATV systems, required by third-party algorithm providers to meet system branding certification. The analog input is provided by 95 dB dynamic range (DNR) ADCs, and analog output is provided by 94 dB DNR DACs. The main speaker outputs can be supplied as a digitally modulated PWM stream to support digital amplifiers. The ADAV4601 includes multichannel digital inputs and outputs. In addition, digital input channels can be routed through integrated sample rate converters (SRC), which are capable of supporting any arbitrary sample rate from 5 kHz to 50 kHz. |
