R
Compliance
The value of the compliance resistor, R
Compliance
sets the
USB2.0 signaling rate (frequency) deviation to 1000ppm
peak-to-peak (+/-500ppm). It causes a -4dB peak power
EMI reduction at the 480MHz fundamental USB2.0
frequency. Higher harmonics are reduced more.
If the R
Compliance
is set to a lower value than its compliance
limit, it will set the USB2.0 signaling rate (frequency)
deviation to above 1000ppm peak-to-peak. For settings
above 1000ppm the USB2.0 compliance pass/fail
becomes gradually intermittent. USB2.0 functionality is
maintained upto 3000ppm peak-to-peak signaling rate
(frequency) deviation. The EMI tradeoff in the system is
attenuation/compliance. While fully functional (and
compliant intermittent) the 2000ppm frequency deviation
can provide -7dB of EMI attenuation at the 480MHz
fundamental.
