w WM8716 High Performance 24-bit, 192kHz Stereo DAC DESCRIPTION FEATURES The WM8716 is a high performance stereo DAC designed for audio applications such as CD, DVD, home theatre systems, set top boxes and digital TV. The WM8716 supports data input word lengths from 16 to 24-bits and sampling rates up to 192kHz. The WM8716 consists of a serial interface port, digital interpolation filter, multi-bit sigma delta modulator and stereo DAC in a small 28-lead SSOP package. The WM8716 also includes a digitally controllable mute and attenuator function on each channel. • 112dB SNR (‘A’ weighted @ 48kHz), THD: -97dB @ -1dB FS • • • Sampling frequency: 8kHz to 192kHz Selectable digital filter roll-off Optional interface to industry standard external filters • • • Differential mono mode Input data word: 16 to 24-bit Hardware or SPI compatible serial port control modes: The internal digital filter has two selectable roll-off characteristics. A sharp or slow roll-off can be selected dependent on application requirements. Additionally, the internal digital filter can be by-passed and the WM8716 used with an external digital filter. The WM8716 supports two connection schemes for audio DAC control. The SPI-compatible serial control port provides access to a wide range of features including onchip mute, attenuation and phase reversal. A hardware controllable interface is also available. − • Hardware mode: mute, de-emphasis, audio format control − Serial mode: mute, de-emphasis, attenuation (256 steps), phase reversal Compatible upgrade to PCM1716 APPLICATIONS • • • CD, DVD audio Home theatre systems Set top boxes • Digital TV BLOCK DIAGRAM WOLFSON MICROELECTRONICS plc To receive regular email updates, sign up at http://www.wolfsonmicro.com/enews/ Production Data, August 2008, Rev 4.2 ©2008 Wolfson Microelectronics plc WM8716 Production Data TABLE OF CONTENTS DESCRIPTION .......................................................................................................1 FEATURES.............................................................................................................1 APPLICATIONS .....................................................................................................1 BLOCK DIAGRAM .................................................................................................1 TABLE OF CONTENTS .........................................................................................2 PIN CONFIGURATION...........................................................................................3 ORDERING INFORMATION ..................................................................................3 ABSOLUTE MAXIMUM RATINGS.........................................................................4 RECOMMENDED OPERATING CONDITIONS .....................................................4 ELECTRICAL CHARACTERISTICS ......................................................................5 TERMINOLOGY ............................................................................................................ 6 PIN DESCRIPTION ................................................................................................8 DEVICE DESCRIPTION.........................................................................................9 SYSTEM CLOCK .......................................................................................................... 9 AUDIO DATA INTERFACE ..................................................................................10 NORMAL SAMPLE RATE ........................................................................................... 10 8 X FS INPUT SAMPLE RATE .................................................................................... 11 MODES OF OPERATION ........................................................................................... 12 HARDWARE CONTROL MODES ............................................................................... 12 SOFTWARE CONTROL INTERFACE......................................................................... 13 REGISTER MAP ......................................................................................................... 13 MUTE MODES ............................................................................................................ 18 FILTER RESPONSES ................................................................................................. 19 APPLICATIONS INFORMATION .........................................................................22 RECOMMENDED EXTERNAL COMPONENTS .......................................................... 22 RECOMMENDED EXTERNAL COMPONENTS VALUES ........................................... 22 PACKAGE DIMENSIONS ....................................................................................25 IMPORTANT NOTICE ..........................................................................................26 ADDRESS: .................................................................................................................. 26 w PD, Rev 4.2,August 2008 2 WM8716 Production Data PIN CONFIGURATION LRCIN 1 28 ML/I2S DIN 2 27 MC/DM1 BCKIN 3 26 MD/DM0 CLKO 4 25 MUTEB XTI 5 24 MODE XTO 6 23 CSBIWO DGND 7 22 RSTB DVDD 8 21 ZERO AVDDR 9 20 AVDDL AGNDR 10 19 AGNDL VMIDR 11 18 VMIDL DIFFHW MODE8X 12 17 VOUTR 13 16 VOUTL 15 AVDD AGND 14 ORDERING INFORMATION DEVICE TEMPERATURE RANGE PACKAGE MOISTURE SENSITIVITY LEVEL PEAK SOLDERING TEMPERATURE WM8716SEDS/V -25 to +85°C 28-lead SSOP (Pb- free) MSL2 260°C WM8716SEDS/RV -25 to +85°C 28-lead SSOP (Pb- free, tape and reel) MSL2 260°C Note: Reel quantity = 2,000 w PD, Rev 4.2, August 2008 3 WM8716 Production Data ABSOLUTE MAXIMUM RATINGS Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at or beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test conditions specified. Wolfson tests its package types according to IPC/JEDEC J-STD-020B for Moisture Sensitivity to determine acceptable storage conditions prior to surface mount assembly.
