WM8753L Hi-Fi and Telephony Dual CODEC The WM8753L is a low power, high quality stereo CODEC with integrated Voice CODEC designed for portable digital telephony applications such as mobile phone, or headset with hi-fi playback capability. The device integrates dual interfaces to two differentially connected microphones, and includes drivers for speakers, headphone and earpiece. External component requirements are reduced as no separate microphone or headphone amplifiers are required, and Cap-less connections can be made to all loads. Advanced on-chip digital signal processing performs tone control, Bass Boost and automatic level control for the microphone or line input through the ADC. The two ADCs may be used to support Voice noise cancellation in a partnering DSP, or for stereo recording. The WM8753L hi-fi DAC can operate as a master or a slave, with various master clock frequencies including 12 or 24MHz for USB devices, 13MHz or 19.2MHz for cellular systems, or standard 256fs rates like 12.288MHz and 24.576MHz. Internal PLLs generate all required clocks for both Voice and hi-fi converters. If audio system clocks already exist, the PLLs may be committed to alternative uses. The WM8753L operates at a nominal supply voltage of 2V, although the digital core can operate at voltages down to 1.42V to save power, and the maximum for all supplies is Volts. Different sections of the chip can also be powered down under software control. • Hi-fi DAC interfaced over I2S type link • Audio sample rates: 8, 16, 24, 32, 48, 96 • DAC SNR 98dB, THD -84dB ‘A’ weighted 48kHz • ADC SNR 95dB, THD -82dB ‘A’ weighted 48kHz • On-chip Headphone Driver with cap-less output option - 40mW output power on / 3.3V - with load SNR 90dB, THD - with load SNR 94dB, THD • On-chip speaker driver with 0.5W into 8R • Voice CODEC interfaced over Voice interface • supports sample rates from 8ks/s to 48ks/s • ADC and DAC SNR 82dB, THD -74dB • Two Differential Microphone Interfaces - Dual ADCs support noise cancellation in external DSP - Programmable ALC / Noise Gate • Low-noise bias supplied for electret microphones Other Features • On-chip PLLs supporting 12, 13, 19.2MHz and other clocks • Cap-less connection options to headphones, earpiece, spkr. • Low power, low voltage - 1.8V to 3.6V digital core 1.42V to 3.6V - power consumption <20mW all-on with 2V supplies - <12mW for PCM CODEC operation • 7x7x0.9mm QFN package • MP3 Player / Recorder mobile phone • Bluetooth stereo headset WOLFSON MICROELECTRONICS plc To receive regular email updates, sign up at Production Data TABLE OF CONTENTS WM8753L 1 FEATURES 1 APPLICATIONS 1 TABLE OF 2 PIN CONFIGURATION - QFN 4 ORDERING 4 PIN 5 ABSOLUTE MAXIMUM RATINGS 6 SIMULATED THERMAL PROPERTIES 6 RECOMMENDED OPERATING 6 ELECTRICAL CHARACTERISTICS 7 TERMINOLOGY 9 OUTPUT PGA’S LINEARITY 10 POWER CONSUMPTION 11 SIGNAL TIMING REQUIREMENTS 12 SYSTEM CLOCK TIMING 12 MODE/GPIO3 AND CSB/GPIO5 LATCH ON POWERUP TIMING 12 AUDIO INTERFACE TIMING MASTER MODE 13 AUDIO INTERFACE TIMING SLAVE MODE 14 CONTROL INTERFACE TIMING 3-WIRE MODE 15 CONTROL INTERFACE TIMING 2-WIRE MODE 16 INTERNAL POWER ON RESET CIRCUIT 17 DEVICE DESCRIPTION 18 INTRODUCTION 18 INPUT SIGNAL PATH 20 MICROPHONE 24 PGA CONTROL 28 AUTOMATIC LEVEL CONTROL ALC 31 3D STEREO ENHANCEMENT 34 OUTPUT SIGNAL PATH 36 ANALOGUE 42 HEADPHONE SWITCH 46 HEADPHONE OUTPUT 47 INTERRUPT CONTROLLER 48 GENERAL PURPOSE INPUT/OUTPUT 51 DIGITAL AUDIO INTERFACES 53 AUDIO INTERFACES 58 CONTROL 62 MASTER CLOCK AND PHASE LOCKED LOOP 66 AUDIO SAMPLE 69 POWER 71 POWER MANAGEMENT 72 REGISTER MAP 77 DIGITAL FILTER CHARACTERISTICS 79 TERMINOLOGY 80 DAC FILTER RESPONSES 81 ADC FILTER RESPONSES 82 VOICE FILTER RESPONSES 84 VOICE DAC FILTER RESPONSES 84 VOICE ADC FILTER RESPONSES 84 WM8753L Production Data DE-EMPHASIS FILTER 85 HIGHPASS FILTER 86 APPLICATIONS INFORMATION 88 Production Data PIN CONFIGURATION WM8753L VXDIN SCLK SDIN CSB/GPIO5 MODE/GPIO3 GPIO4 MIC2N MIC2 MIC1N MIC1 RXN RXP GP2/CLK2 GP1/CLK1 PGND PVDD HPVDD OUT4 OUT3 ROUT1 LOUT1 HP/SPKRGND ROUT2 LOUT2 TOP VIEW ORDERING INFORMATION ORDER CODE WM8753CLGEFL/V TEMPERATURE RANGE -25C to +85C WM8753CLGEFL/RV -25C to +85C Note Reel quantity = 2,200 PACKAGE 48-lead QFN 7x7x0.9mm Pb-free 48-lead QFN 7x7x0.9mm Pb-free, tape and reel MOISTURE SENSITIVITY LEVEL MSL3 MSL3 PEAK SOLDERING TEMPERATURE 260oC 260oC WM8753L Production Data PIN DESCRIPTION NAME TYPE VXDOUT Digital Output Voice ADC Output VXCLK Digital Input/Output Voice CODEC data clock / ADC frame clock VXFS Digital Input/Output Voice CODEC Frame Sync Digital Input/Output DAC Frame Sync BCLK Digital Input/Output DAC data clock input / output ADCDAT Digital Output ADC Digital Audio Data Alternative Output DACDAT Digital Input DAC Digital Audio Data Input MCLK The Moisture Sensitivity Level for each package type is specified in Ordering Information.
