2.5.3
The IR transceiver circuit uses a Vishay
Footprints for an optional optical transceiver are implemented. These footprints are for
the Vishay TFDU 4100 and the Agilent
three implementations to be installed, but with only one connected to the MCP215X or
MCP2140 TXIR and RXIR pins.
The MCP2140 also requires the Optical Transceivers’s RXD signal to be conditioned
to be used as the input to the MCP2140’s RXPD/RXPDREF signals.
2.5.3.1
If you wish to test with either of the other optical transceivers, the TFDU 4300’s RXD
and TXD signals need to be electrically removed. This is done by cutting the trace
between the jumper JP1C pins and the trace between the jumper JP2C pins. This
location is shown in Figure 2-6.
Also the components for the desired optical transceiver need to be installed. See
Appendix B. “Bill of Materials (BOM)”.
