3.1 Functional Block Descriptions
3.3V LDO Regulator
The 3.3V LDO Regulator generates the 3.3 volt
reference voltage for driving the USB transceiver
cell output buffers. It requires an external
decoupling capacitor to be attached to the 3V3OUT
regulator output pin. It also provides 3.3V power to
the RSTOUT# pin. The main function of this block
is to power the USB Transceiver and the Reset
Generator Cells rather than to power external logic.
However, external circuitry requiring 3.3V nominal
at a current of not greater than 5mA could also
draw its power from the 3V3OUT pin if required.
USB Transceiver
The USB Transceiver Cell provides the USB 1.1 /
USB 2.0 full-speed physical interface to the USB
cable. The output drivers provide 3.3 volt level slew
rate control signalling, whilst a differential receiver
and two single ended receivers provide USB data
in, SEO and USB Reset condition detection.
USB DPLL
The USB DPLL cell locks on to the incoming NRZI
USB data and provides separate recovered clock
and data signals to the SIE block.
