RS422/RS485 Applications
The receivers on the LTC1345 are ideal for RS422 and
RS485 applications. Using the test circuit in Figure 9, the
LTC1345 receivers are able to successfully reconstruct
the data stream with the common-mode voltage meeting
RS422 and RS485 requirements (12V to – 7V).
Figures 10 and 11 show that the LTC1345 receivers are
very capable of reconstructing data at rates up to 10Mbaud.
