WM8594 24-bit 192kHz 2Vrms Multi-Channel CODEC The WM8594 is a high performance multi-channel audio CODEC with flexible input/output selection and digital and analogue volume control. Features include a 24-bit stereo ADC with digital gain control, two 24-bit DACs with independent volume control and clocking, and a range of input/output channel selection options with analogue volume control for flexible routing within current and future audio systems. The WM8594 has a five stereo input selector which accepts input levels up to 2Vrms. One stereo input can be routed to the ADC. All inputs can be routed to an output selector. The WM8594 outputs three stereo audio channels at line levels up to 2Vrms, which can be selected from any of the analogue inputs and DAC outputs. Additionally, one stereo output is available with a headphone driver. The DAC channels include independent digital volume control, and all three stereo output channels include analogue volume control with soft ramp. The WM8594 supports up to 2Vrms analogue inputs, 2Vrms outputs, with sampling rates from 32kHz to 192kHz for the DACs, and 32kHz to 96kHz for the ADC. The WM8594 is controlled via a serial interface with support for 2-wire and 3-wire control with full readback. Control of mute, powerdown and reset can also be achieved by pin selection. The WM8594 is ideal for audio applications requiring high performance and flexible routing options, including flat panel digital TV and DVD recorder. The WM8594 is available in a 48-lead TQFP package. • Multi-channel CODEC with 5 stereo input selector and 3 stereo output selector • 4-channel DAC, 2-channel ADC • 5x2Vrms stereo input selector with 3x2 channel analogue bypass to output selector • 3x2Vrms stereo output selector • Stereo headphone driver • Audio performance - DAC 100dB SNR typical ‘A’ weighted 48kHz - DAC -87dB THD typical - ADC 96dB SNR typical ‘A’ weighted 48kHz - ADC -80dB THD typical • Independent sampling rate for ADC and DACs • Independent sampling rate for DAC1 and DAC2 • DACs sampling frequency 32kHz 192kHz • ADC sampling frequency 32kHz 96kHz • DAC digital volume control +12dB to -100dB in 0.5dB steps • ADC digital volume control from +30dB to -97dB in 0.5dB steps • ADC input analogue boost control, selectable from 0dB, +3dB, +6dB and +12dB • Output analogue volume control +6dB to -73.5dB in 0.5dB steps with zero cross or soft ramp to prevent pops and clicks • Headphone drive capability on one stereo output with jack detect • 2 and 3-wire serial control interface with readback and hardware reset, mute and powerdown pins • Independent master or slave clocking modes • Programmable format audio data interface modes - I2S, LJ, RJ, DSP • 3.3V / 9V analogue, 3.3V digital supply operation • 48-lead TQFP package • Digital Flat Panel TV • DVD-RW WOLFSON MICROELECTRONICS plc To receive regular email updates, sign up at WM8594 BLOCK DIAGRAM Production Data ADCREFP ADCREFN /RESET MUTE /PWDN MODE /CS SDIN SCLK SDOUT DOUT ADCMCLK ADCBCLK ADCLRCLK DIN1 DACMCLK1 DACBCLK1 DACLRCLK1 DIN2 DACMCLK2 DACBCLK2 DACLRCLK2 DACREFP DACVMID DACREFN AVDD1 ADCVMID AGND1 Stereo ADC ADC Input Mux Control Interface Audio Interface Volume Control Digital Filters Volume Control Matrix Channel Selection Volume Control Matrix Channel Selection Stereo DAC1 Stereo DAC2 VIN1L VIN1R VIN2L VIN2R VIN3L VIN3R VIN4L VIN4R VIN5L VIN5R wWM8594 PGA Input Mux PGA1L PGA1R PGA2L PGA2R PGA3L PGA3R Output Mux DVDD DGND AVDD2 AGND2 VOUT1L VOUT1R VOUT2L VOUT2R VOUT3L VOUT3R Production Data DESCRIPTION APPLICATIONS BLOCK DIAGRAM PIN ORDERING INFORMATION PIN DESCRIPTION ABSOLUTE MAXIMUM THERMAL PERFORMANCE RECOMMENDED OPERATING CONDITIONS SUPPLY CURRENT CONSUMPTION ELECTRICAL CHARACTERISTICS TERMINOLOGY 10 MASTER CLOCK TIMING 11 /RESET TIMING 11 DIGITAL AUDIO INTERFACE TIMING SLAVE 12 DIGITAL AUDIO INTERFACE TIMING MASTER 13 CONTROL INTERFACE TIMING 2-WIRE MODE 14 CONTROL INTERFACE TIMING 3-WIRE MODE 15 POWER ON RESET POR 16 DEVICE INTRODUCTION 17 CONTROL 18 2-WIRE SM-BUS COMPATIBLE SERIAL CONTROL INTERFACE MODE 18 3-WIRE SPI COMPATIBLE SERIAL CONTROL INTERFACE MODE 20 DIGITAL AUDIO DATA FORMATS 21 DIGITAL AUDIO INTERFACE 26 DIGITAL AUDIO DATA SAMPLING 29 DAC 30 ADC 33 ANALOGUE ROUTING 35 POP AND CLICK PERFORMANCE 45 GLOBAL ENABLE 47 EMERGENCY POWER 48 REGISTER DIGITAL FILTER CHARACTERISTICS DAC FILTER 73 DIGITAL DE-EMPHASIS 74 ADC FILTER 75 ADC High Pass 75 APPLICATIONS INFORMATION RECOMMENDED EXTERNAL COMPONENTS 76 RECOMMENDED ANALOGUE LOW PASS FILTER 77 EXTENDED INPUT IMPEDANCE 77 RELEVANT APPLICATION NOTES 78 PACKAGE DIMENSIONS IMPORTANT NOTICE ADDRESS 80 WM8594 PIN CONFIGURATION Production Data ORDERING INFORMATION DEVICE WM8594SEFT/V TEMPERATURE RANGE -40 to +85oC WM8594SEFT/RV -40 to +85oC Note Reel quantity = 2,200 PACKAGE 48-lead TQFP Pb-free 48-lead TQFP Pb-free, tape and reel MOISTURE SENSITIVITY LEVEL MSL3 MSL3 PEAK SOLDERING TEMPERATURE Production Data PIN DESCRIPTION NAME ADCLRC ADCBCLK DOUT DACMCLK1 DACLRC1 DACBCLK1 DIN1 DACMCLK2 DACLRC2 DACBCLK2 DIN2 DVDD DGND /PWDN MUTE /RESET AVDD2 AGND2 VOUT3R VOUT3L VOUT2R VOUT2L VOUT1R VOUT1L VIN1L The Moisture Sensitivity Level for each package type is specified in Ordering Information.
