DC Characteristics
USB Host Transceiver Characteristics
Every VDD pin, including USB VDD, must 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
(0.1μF, 6V) between the pin itself and a good ground. Keep
capacitor leads as short as possible. Use surface mount
capacitors with the shortest traces possible (the use of a
ground plane is strongly recommended).
This product was tested as compliant to the USB-IF specifi-
cation under the test identification number (TID) of 40000689
and is listed on the USB-IF’s integrators list.

Notes
13.ICC measurement includes USB Transceiver current (IUSB) operating at full speed.
14.ICCsus1 measured with 12 MHz Clock Input and Internal PLL enabled. Suspend set –(USB transceiver and internal Clocking disabled).
15.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.
16.All typical values are VDD = 3.3V and TAMB= 25°C.
17.ZUSBX impedance values includes an external resistor of 24 Ohms ± 1% (SL811HS revision 1.2 requires external resistor values of 33 Ohms ±1%).
