The USB specification offers a 1.5 Mbps data transfer
rate known as Low-Speed which requires a 1.5 k
pull-up
resistor to be connected to the D- line. Slew rate control is
accomplished with 47pF attached to the transceiver before
the R
S
.
Voltage Supply (Vbus) is connected to Pin 1
Ground is connected to Pin 6
D+ from the connector is routed to Pin 2 and Pin 5
to the D+ line of the USB Transceiver
D- from the connector is routed to Pin 3 (1.5 k
pull-
up resistor) and Pin 4 to the D- line of the USB Transceiver
cable

ELECT ROMAGNET IC EMIS S ION AND S US CEPT ABILIT Y
FCC Part 15 sets limits for maximum allowable EM
emission and susceptibility. There are two types of
emissions. Conducted emissions with frequency of
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,
control cards, interface boards, external memory expansion
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.
