4. FUNCTIONAL DESCRIPTION
4.1.
Overview
The STIr4200 consists of two major functional blocks, the USB controller and the
digital IR transceiver. The USB controller provides a Control, Bulk-In, and Bulk- Out
endpoints to the USB host. The digital IR transceiver consists of a transmit and
receive interface that connects to an analog IR front end. Figure 1shows a block dia-
gram of the device.
This USB/IrDA Bridge Controller has full interface capability to connect between a
USB bus , and an IrDA-compatible infrared transceiver device. A simplified sche-
matic of this arrangement is shown in Figure 2.
