Booster Interface

EZ-OTG has an on-chip power booster circuit for use with power supplies that range between 2.7V and 3.6V. The booster circuit boosts the power to 3.3V nominal to supply power for the entire chip. The booster circuit requires an external inductor, diode, and capacitor. During power down mode, the circuit is disabled to save power. Figure 2 shows

Crystal Interface

The recommended crystal circuit to be used with EZ-OTG is shown in Figure 4. If an oscillator is used instead of a crystal circuit, connect it to XTALIN and leave XTALOUT uncon- nected. For further information on the crystal requirements, see Table 39, “Crystal Requirements,” on page 65.

XTALIN

Component details:

•L1: Inductor with inductance of 10 µH and a current rating of at least 250 mA

•D1: Schottky diode with a current rating of at least 250 mA

•C1: Tantalum or ceramic capacitor with a capacitance of at least 2.2 µF

Figure 3 shows how to connect the power supply when the booster circuit is not being used.
