6 Connection Diagram, LQFP-48VS10036 CONNECTION DIAGRAM, LQFP-48Figure 7: Typical Connection Diagram Using LQFP-48.The common buffer GBUF can be used for common voltage (1.24 V) for earphones. This willeliminate the need for large isolation capacitors on line outputs, and thus the audio output pinsfrom VS1003 may be connected directly to the earphone connector.GBUF must NOT be connected to ground under any circumstances. If GBUF is not used,LEFT and RIGHT must be provided with coupling capacitors. To keep GBUF stable, you shouldalways have the resistor and capacitor even when GBUF is not used. See application notes fordetails.Unused GPIO pins should have a pull-down resistor.If UART is not used, RX should be connected to IOVDD and TX be unconnected.Do not connect any external load to XTALO.Note: This connection assumes SM_SDINEW is active (see Chapter 8.6.1). If also SM_SDISHAREis used, xDCS should be tied high (see Chapter 7.2.1).Version: 1.06, 2012-03-16 15
