and USB 2.0 Full Speed specification for device
termination, EMI filtering and ESD protection. The R
resistor provides the proper signal termination; the 47pF
capacitor controls the signal rise and fall slew; the TVS
diodes protect the IC from ESD damage; and the total
capacitance and resistance creates a low pass filter
eliminating the high frequency energy from the circuit.

emissions.
emission of 0.45 to 30 MHz and Radiated emissions
with frequency of emission of 30 MHz to 40 GHz. All
digital computing devices including the peripheral
devices must comply. Examples of peripheral devices
include terminals, printers, external floppy disk drives
and other data storage devices, video monitors,

expansion cards and other input/output devices that may or
may not contain digital circuitry. LX7201 is optimized to
minimize the radiated EMI which is the primary concern in
devices using USB. Refer to the typical filter response
curve for the attenuation characteristics of LX7201 over the
frequency range of 30KHz to 6GHz.
