transfer rate known as Low-Speed which requires a 1.5 k Ω
pull-up resistor to be connected to the D- line. Slew rate
control is accomplished with 47pF attached to the
transceiver before the R
FCC Part 15 sets limits for maximum allowable EM
emission and susceptibility. There are two types of
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 fixed
adjustable data storage devices, video monitors, keyboards,

EMI Filter & ESD Protection for Up Stream USB
cards and other input/output devices that may or may not
contain digital circuitry. LX7202 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 LX7202 over the
frequency range of 30KHz to 6GHz.
