Digital Amplifier Controllers SymphonyTM FSA95601 Freescale Semiconductor's Symphony FSA95601 is a high-performance six-channel SymphonyTM FSA95601 Class D digital amplifier controller designed for high-quality audio amplifiers. This PLL NPWM I2C/SPI solution yields a significant improvement in performance over typical Class D amplifiers, where inherently noisy electrical systems in the environment severely affect SAI REF OSC audio performance. The Symphony FSA95601 can process up to six channels of pulse code modulation INS Processor Volume (PCM) digital audio input data to produce UP Sample the corresponding pulse-width modulation (PWM) outputs to drive external power stages. Input Queue ASRC This device utilizes patented high-performance digital feedback technology to achieve PWM Drivers superior audio performance and power supply rejection. This device is part of a total digital audio amplifier system chip set offered by Freescale, where small physical Feedback size and weight, high power efficiency, high audio performance and low electromagnetic interference (EMI) are demanded. The device is designed to support automotive quality requirements and Features * Dynamic range >100 dB1, unweighted ambient conditions. * Six-channel high-performance digital PWM * Suppressed carrier mode eliminates the modulator Freescale's Class D amplifier controllers are ideal for audio applications in the home, car and professional studio. * Capable of 100 percent depth of modulation, enabling maximum audio power output from the available power supply rails * Patented high-performance digital feedback technology corrects for power stage non-idealities and rejects power supply noise while maintaining superior audio performance * Low distortion (Typical THD+N<0.01 percent, 20-20 kHz, with 1 kHz, -3dB FS (12W) input, 14.4V power supply, 4 Ohm load1) 1Measured using FSA95601 EVM board with discrete, H-bridge power stage, Audio Precision AUX 25 and AES17 filters PWM pulse repetition frequency and its odd harmonics in the differential PWM output, reducing EMI emissions * Pop- and click-free power-on/off feature with proprietary Freescale technology * Artifact-free digital volume control * 12 mm x 12 mm, 80-pin exposed pad (EP) TQFP (thin quad flat pack) package * 3.3V power supply * Automotive AEC-Q100 qualified Digital Audio Modulator Audio/Volume Control Host Interface * Multi-stage upsampler and selectable * Independent six-channel mute and * Serial host controller (SPI or I2C) de-emphasis filter * Choice of steep or gentle upsampling filter * Built-in asynchronous sample rate converter (ASRC) for synchronization to sources with sampling rates from 32 kHz to 192 kHz * Automatic audio sample rate detection and upsampling * Patented high-performance digital PWM noise shaper volume control * I2C addressing allows up to four unique * Master volume control for controlling all six channels with one command * Volume change modes: ramp, zero power stages * Supports half-bridge and full-bridge configurations * Supports both standard and suppressed carrier modulation modes How to Reach Us: Home Page: www.freescale.com e-Mail: support@freescale.com * Interrupt pin flags internal error conditions * 5-volt tolerant host I/O crossing, ramp plus zero crossing * Hardware and software mute controls On-Chip Peripherals * Volume range +18 dB to -96 dB in * Fully integrated, low jitter programmable 1/8 dB steps phase-lock loop (PLL) clock generator * Quiet-enable for digital silence * Clock oscillator operates from 12, 24 or Audio Interface * Built-in power-on-reset (POR) circuit * Programmable modulation guard time and pulse time to adapt to various devices on a single I2C bus 48 MHz quartz crystals * Supports time division multiplexing (TDM), stereo and I2S: 24-bit left/right justified, 16bit right justified Availability * Samples available now * 5-volt tolerant audio I/O * Production Q3 2007 Europe, Middle East and Africa: Asia/Pacific: Freescale Halbleiter Deutschland GmbH Freescale Semiconductor Hong Kong Ltd.
