Evaluation Kit for the MXL1543, MXL1544, MAX3175, MXL1344A


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.
