DC Characteristics
USB Host Transceiver Characteristics
Every V
DD
pin, including USB V
DD
, must have a decoupling
capacitor to ensure clean V
DD
(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. 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.
