1 / 21 page  WM8716 High Performance 24-bit, 192kHz Stereo DAC Production Data, April 2001, Rev 3.1 WOLFSON MICROELECTRONICS LTD Lutton Court, Bernard Terrace, Edinburgh, EH8 9NX, UK Tel: +44 (0) 131 667 9386 Fax: +44 (0) 131 667 5176 Email: sales@wolfson.co.uk www.wolfsonmicro.com Production Data Datasheets contain final specifications current on publication date. Supply of products conforms to Wolfson Microelectronics’ Terms and Conditions. 2001 Wolfson Microelectronics Ltd . DESCRIPTION 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-pin SSOP package. The WM8716 also includes a digitally controllable mute and attenuator function on each channel. 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 on- chip mute, attenuation and phase reversal. A hardware controllable interface is also available. FEATURES • 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: − 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 SERIAL INTERFACE MUTE/ ATTEN CONTROL INTERFACE BCKIN (3) (16) VOUTL (13) VOUTR SIGMA DELTA MODULATOR LRCIN (1) DIN (2) AGNDR (10) AVDDR (9) MUTE/ ATTEN SIGMA DELTA MODULATOR DIGITAL FILTERS MODE8X (12) (5) XTI (6) XTO (4) CLKO MUX (8) DVDD (15) AVDD (14) AGND (7) DGND MUTEB (25) DIFFHW (17) MD/DM0 (26) MC/DM1 (27) ML/I2S (28) MODE (24) CSBIWO (23) RSTB (22) ZERO (21) LOW PASS FILTER LOW PASS FILTER (11) VMIDR MUX (18) VMIDL CRYSTAL/OSC RIGHT DAC LEFT DAC (19) AGNDL (20) AVDDL.
