The MXL1543 evaluation kit (EV kit) combines Maxim's
multiprotocol clock/data transceiver (MXL1543), control
transceiver (MXL1544), and cable terminator (MXL1344A)
chips. This chipset forms a complete software-selectable
multiprotocol data terminal equipment (DTE) or data communications
equipment (DCE) interface port.
The MXL1543, MXL1544, and MXL1344A chipset supports
V.28 (RS-232), V.11(RS-449/V.36, EIA530, EIA530-
A, X.21), and V.35 protocols. NET1, NET2, TBR-1, and
TBR-2 compliance has been certified by TUV Telecom
Services, Inc. Internal charge pumps allow this kit to operate
off a single +5V supply.
The MXL1543 EV kit was designed to take advantage of
the chipset's flow-through pinout. This kit includes a 40-
pin header (logic signals), a female DB25 connector (protocol
signals), three SMA connectors (high-speed logic
signals), and scope probe connectors for measuring the
high-speed data signals (logic and protocol signals).
The MXL1543 EV kit can evaluate the MAX3175 and is
used in place of the MXL1544. Contact Maxim to order
samples of the MAX3175CAI. No further changes
are required to the board to evaluate the MAX3175.
