LTD D|O3202B·Rev.0.5 D|o3202B Applications Design Guide DIO3202B is used in applications where the slim and thin smart phone designs are expected. By sharing the USB connector between USB2.0 data lines and audio headphone outputs the designers can eliminate the using of bulky headphone jacks. Meanwhile, using the mini-U SB connectors as audio outputs allows the end users to reduce the cost to buy too many different types of cell phone accessories DIO3202B unique architectures allow the part to allow the part to have constant Ron, Ron(flatness)and THD T performance independent of Vcc supply value. So in some applications such as mobile cell phone designs, if theoD designers want to achieve the lowest standby power consumption when the battery is turned OFF, it is highly recommended that DIO3202B be powered by 2. 8V, no need of being powered by 4. 3V directly. This will hep3 designers to be freed from the complex logic designs to ensure the part will get into sleep mode DIO3202B's control pins are 1.8V control logic compatible, so the parts can be controlled by baseband processor GPlO directly without worrying about the level shifting issues Regarding high speed signal integrity, DIO3202B is recommended to be placed as close as possible to the USB controller outputs to reduce the signal reflection under high speed mode(480Mbps). In the meanwhile, the Vcc pins of DIO3202B is required to have decouplings capacitors to reduce the supply ripples The below is the DIO3202B USB 2.0 high speed(480Mbps)eye diagram compliance test under near-end modes (most challenging mode) 28V 10nF D USB Host DIO3202A/B Device ≤ Figure 2.
