1 / 35 page  WM9704Q 4-Channel Surround Sound Codec Production Data, January 2001, Rev 2.3 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 http://www.wolfson.co.uk 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 WM9704Q is a high quality audio codec compliant with the AC’97 Revision 2.1 specification. It performs full duplex 18-bit codec functions from 8 to 48k samples/s and offers excellent quality with high SNR. Features include 3D sound and line-level outputs. Support is also provided for variable sample rates and master/slave mode operation. Additionally the WM9704Q provides two proprietary modes: 4-channel quad mode enables two channels of ADC and DAC plus an additional two DAC channels as rear outputs. 6-channel mode configures the device to provide external support for two additional stereo outputs via the GPIO pins. WM9704Q is interchangeable with AC’97 Codecs from Wolfson and other suppliers in the basic Revision 2.1 mode. WM9704Q is fully operable with 3.3V or 5.0V or mixed 3.3/5.0V supplies and is packaged in an industry standard 48-pin TQFP package. FEATURES • 4 DAC channels, stereo ADC • Balanced mixer architecture • S/N ratio > 95dB • Variable rate audio and modem support • Analogue 3D stereo enhancement • Line level outputs • Master/slave ID selection • Low power implementation • 3.3V or 5V operation • 48-pin TQFP package APPLICATIONS • 4-channel surround sound solution implemented with 2 additional internal DACs • 6-channel surround sound supported via connection of a stereo DAC (WM8725) to GPIO pins • Supports 4-channel playback of analogue sources such as CD BLOCK DIAGRAM (2) XTLIN (3) XTLOUT Σ Σ MUX (37) MONOOUT (39,41) LINEOUT (REAR) (35,36) LINEOUT (FRONT) Σ (45) CID0 (46) CID1 (43,44,48) GPIO[1:3] (6) BITCLK (10) SYNC (8) SDATAIN (5) SDATAOUT (11) RESETB (47) EAPD (30) MODE0 (40) MODE1 REV. 2.1 SWITCH REAR STEREO DAC SRC SERIAL I/F KEY: MONO STEREO VOL/ MUTE VOL/ MUTE VOL/ MUTE VOL/ MUTE VOL/ MUTE VOL/ MUTE VOL/ MUTE VOL/ MUTE FRONT STEREO DAC SRC VOL/ MUTE VOL/ MUTE VOL/ MUTE VOL/ MUTE VOL/ MUTE VOL/ MUTE Σ Σ CD (18,20) LINEIN (23,24) VIDEO (16,17) AUX (14,15) PHONE (13) PCBEEP (12) MIC[1] (21) MIC[2] (22) 0dB/ 20dB MASTER/ SLAVE SELECT GENERAL IO SUPPORT OSC 3D VOL STEREO ADC SRC MUX RECORD MUX AND MUTE SERIAL I/F WM9704Q |
