@ FS
Every VDD pin, including USB VDD, has to have a decoupling capacitor to ensure clean VDD (free of high-frequency noise) at the
chip input point (pin) itself.
The best way to do this is to connect a ceramic capacitor (0.1 µF, 6V) between the pin itself and a good ground. Capacitor leads
must be kept as short as possible. Use surface mount capacitors with the shortest traces possible (the use of a ground plane is
strongly recommended).
Notes:

CCsus1 measured with 12-MHz Clock Input and Internal PLL enabled. Suspend set –(USB transceiver and internal Clocking disabled).
ICCsus2 measured with external Clock, PLL disabled, and Suspend set. For absolute minimum current consumption, ensure that all inputs to the device are at
static logic level.
19. All typical values are VDD = 3.3V and TAMB= 25°C.
20. impedance values includes an external resistor of 24 Ohms ± 1% (SL811HS revision 1.2 requires external resistor values of 33 Ohms ±1%).
