at FS
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 (0.1 μF, 6 V) 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 recom-
mended).
This product was tested as compliant to the USB-IF specification under the test identification number (TID) of 40000689 and is listed
on the USB-IF’s integrators list.
Notes
11. I measurement includes USB Transceiver current (I
) operating at full speed.
CC
USB
12. I
measured with 12 MHz Clock Input and Internal PLL enabled. Suspend set –(USB transceiver and internal Clocking disabled).
CCsus1
13. I
measured with external Clock, PLL disabled, and Suspend set. For absolute minimum current consumption, ensure that all inputs to the device are at
CCsus2
static logic level.
14. All typical values are V = 3.3 V and T
= 25°C.

15. Z
impedance values includes an external resistor of 24 Ohms ± 1% (SL811HS revision 1.2 requires external resistor values of 33 Ohms ±1%).
