Optical Transceiver
The MCP2150 requires an infrared transceiver. The
transceiver can be an integrated solution. Table 2-6
shows a list of common manufacturers of integrated
optical transceivers. A typical optical transceiver cir-
cuit, using a Vishay/Temic TFDS4500, is shown in
FIGURE 2-12:
TYPICAL OPTICAL
TRANSCEIVER
CIRCUIT
The optical transceiver logic can be implemented with
discrete components for cost savings. Care must be
taken in the design and layout of the photo detect cir-
cuit, due to the small signals that are being detected
and their sensitivity to noise. A discrete implementation
of the optical transceiver logic is implemented on the
MCP2120 and MCP2150 Developer’s Kit boards.

Note:
The discrete optical transceiver implemen-
tation on the MCP2120 and MCP2150
Developer’s Kit boards may not meet the
IrDA specifications for the physical layer
(IrPHY). Any discrete solution will require
appropriate validation for the user’s
application.
