Universal Serial Bus (USB)
12.5
The recommended line interface is shown in
pull-up resistor is optional.
12.5.1
The USB specification requires that a pull-up resistor must be placed on the D+ signal for the upstream
hub to detect attachment of a full-speed device. The user may optionally want to control the attach/detach
detection by software instead of only at power on and off. With software control of the pull-up resistor, the
user has unlimited time to initialize the USB module. The software controlled pull-up resistor can be
implemented with only a few discrete components. The recommended circuit for implementing software
control of the pull-up resistor is shown in
12.5.2
The device has input protection on all pins and may source or sink a limited amount of current without
damage.
The most important considerations for PCB layout deal with noise: noise on the power supply, noise
generated by the digital circuitry on the device, and noise resulting from coupling digital signals into the
analog signals. The best PCB layout methods to prevent noise–induced problems are as follows:
12-36
•
•
•
Keep digital signals as far away from analog signals (D+ and D-) as possible.
Use short, low inductance traces for the analog circuitry to reduce inductive, capacitive, and radio
frequency noise sensitivities.
Use short, low inductance traces for digital circuitry to reduce inductive, capacitive, and radio
frequency radiated noise.
