software-selectable cable termination chip or by using
existing discrete designs.
A complete DCE-to-DTE interface operating in EIA-530
mode is shown in Figure 10. The first LTC1343 of each port
is used to generate the clock and data signals along with
LL (Local Loop-back) and TM (Test Mode). The second
LTC1343 is used to generate the control signals along with
Figure 10. Complete Multiprotocol Interface in EIA-530 Mode
Overview
The LTC1343 is a 4-driver/4-receiver multiprotocol trans-
ceiver that operates from a single 5V supply. Two LTC1343s
form the core of a complete software-selectable DTE or
DCE interface port that supports the RS232, RS449,
EIA-530, EIA-530-A, V.35, V.36 or X.21 protocols. Cable
termination may be implemented using the LTC1344
