LTC1344
TYPICAL APPLICATIONS N
Figure 13 shows a typical application for the LTC1344
using the LTC1343 mixed mode transceiver chip to gener-
ate the clock and data signals for a serial interface. The
LTC1344 VEE supply is generated from the LTC1343
charge pump and the select lines M0, M1, M2, DCE and
LATCH are shared by both chips. Each driver output and
receiver input is connected to one of the LTC1344 termi-
nation ports. Each electrical protocol can then be chosen
using the digital select lines.
