transfer rate known as Low-Speed which requires a 1.5 kΩ
pull-up resistor to be connected to the D- line. Slew rate
control is accomplished with C

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 data storage

boards, external memory expansion cards and other
input/output devices that may or may not contain digital
circuitry. LX7203 is optimized to minimize the radiated
EMI which is the primary concern in devices using USB.
