AC'97 Revsion2.1 Audio CODEC with Digital Audio I/F
OVERVIEW
YMF743 is an AC'97 Audio CODEC LSI, which is fully compliant with the industry standard "Audio CODEC '97" component specification (Revision 2.1). Different from former AC'97, YMF743 supports new features like SPDIF OUT and Zoomed Video Port. Without using a digital controller, these new features can be enhanced in the AC'97 sound system that has an ICH controller built-in chipset. Low power consumption is supported not only in the normal mode but can be controlled in the power-down mode.
FEATURES
* AC'97 Revision 2.1 Compliant * Exceeds PC98 / PC99 Audio Performance Requirements * Analog Inputs : - 4 Stereo Inputs: LINE, CD, VIDEO, AUX - 2 Monaural Inputs: Speakerphone and PC BEEP Inputs - 2 Independent Microphone Inputs * PC BEEP can directly output to Line Out * Internal +20dB amplifier circuitry for microphone * Analog Outputs : Stereo LINE Output, True LINE Level and Monaural Output * Supports Zoomed Video Port * Supports Consumer IEC958 Output Port (SPDIF OUT) * Supports 3D Enhancement (Wide Stereo), and Bass / Treble control * Multiple CODEC Capability * Programmable Power Down Mode * Supports EAPD (External Amplifier Power Down) * Power Supplies : Analog 5.0V, Digital 3.3V or 5.0V * 48-Pin SQFP Package (YMF743-S)

Power and Ground To get the most out of analog performance, it is necessary to split the ground into analog and digital blocks. Analog ground and digital ground earth at one point closed to the initial ground supply of the board. The layout of the ground pattern should be designed as large as possible and the impudence should be reduced to prevent from receiving ambient noise. In addition, use 0.1 F and 47 F capacitors to connect between the P P analog voltage pin and the analog ground as well as between the digital supply pin and the digital ground. Reference Voltage As the reference voltage determines all analog signals' reference levels of YMF743, noise generated from the reference voltage could affect the YMF743's analog performance. To stabilize the YMF743's reference voltage, insert a 0.1 F ceramic capacitor in parallel with a 22 F capacitor between Vref pin and the ground. P P The 0.1 F ceramic capacitor should be designed as close to the Vref pin as possible P Master Clock To suppress the master clock from affecting its surroundings, it is recommended to keep the master clock guarded on the ground so the noise can be reduced. Unused Analog Input / Output pins For the unused analog input pins, short them through a 0.1 F ceramic capacitor to the analog ground. For P the unused analog output pins, they should be left opened.
