A simplified functional block diagram of
ISOUSB111 is shown in
Figure 8-1. The device comprises the following:
- Transmit and receive circuits and
pull-up and pull-down resistors according to the USB standard.
- Digital logic to handle
bi-directional communication, and various state-transitions.
- Internal LDOs to generate
V3P3Vx
supplies from the VBUSx
supplies.
- Galvanic isolation.
