19-5727; Rev 0; 1/11 MAX13170E/MAX13172E/MAX13174E Evaluation Kit The MAX13170E/MAX13172E/MAX13174E evaluation kit (EV kit) combines the MAX13170E multiprotocol clock/data transceiver, the MAX13172E control transceiver, and the MAX13174E cable terminator chips. This chipset forms a complete software-selectable multiprotocol data terminal equipment (DTE) or data communications equipment (DCE) interface port that supports the V.28 (RS-232), V.11 (RS-449/V.36, EIA-530, EIA-530A, and X.21), and V.35 protocols. Internal charge pumps allow the EV kit to operate off a single 5V supply. The EV kit was designed to take advantage of the chipset’s flow-through pinout. The EV 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).

Quick Start Required Equipment • MAX13170E/MAX13172E/MAX13174E EV kit • 5V DC power supply Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation. Caution: Do not turn on power supplies until all connections are completed. 1) Verify that the default settings are configured correctly, as shown in Tables 1, 2, and 3. 2) Connect a single 5V Q5% power supply between the VCC and GND pads located in the lower-left corner of the EV kit board. 3) The yellow LEDs indicate the protocol mode of the chipset. The LEDs light up when the corresponding signal is a logic-high. Verify that all yellow LEDs light up indicating no-cable mode. All board labels, including all the labels for the LEDs, follow the same label format. The board label format top label corresponds to DCE mode and the bottom label corresponds to DTE mode. 4) The green LEDs are attached to the receiver logic outputs of the MAX13170E (U1) and the MAX13172E (U2). The LEDs light up when the receiver logic outputs are a logic-high. Verify that all green LEDs light up when no signals are attached to the DB25 connector. Note: The receivers have the true fail-safe feature allowing 0V differential voltage to be a valid state that forces the receiver outputs high. 5) The red LEDs are attached to the transmitter logic inputs of U1 and U2. The LEDs light up when the transmitter logic inputs are a logic-high. Verify that none of the red LEDs light up when no signals are connected to the 40-pin header (J1). 2   _______________________________________________________________________________________ MAX13170E/MAX13172E/MAX13174E Evaluation Kit The MAX13170E/MAX13172E/MAX13174E EV kit was designed to take advantage of the chipset’s flow-through pinout. The logic signals have all been routed to the 40-pin header (J1) located on the left side of the EV kit board. The protocol signals have all been routed to the female DB25 connector (J2) located on the right side of the board. Various connectors have been added to the EV kit to aid in taking quality measurements. Leave JU17 unconnected when measuring the supply current of the chipset. Scope-probe connectors have been added to measure the high-speed signals of the transmitter inputs/outputs and receiver inputs/outputs of the MAX13170E. The scope-probe connectors located on the left side of the board are connected to the logic input and output signals. The scope-probe connectors located on the right side of the board are connected to the protocol input and output signals. Three SMA connectors (J3, J4, and J5) have also been provided for driving the high-speed transmitter inputs of the MAX13170E. The string of 16 LEDs across the top of the board (D1–D16) are logic indicators. The red LEDs (D1–D6) indicate the state of the transmitter inputs of the MAX13170E and MAX13172E, the green LEDs (D7–D12) indicate the state of the receiver outputs, and the yellow LEDs (D13–D16) indicate the state of the protocol and the protocol-termination modes. The LEDs light up when their corresponding signals are a logic-high. The EV kit is extremely flexible and has several settings for both the ICs as well as the board. The ICs have been put into no-cable mode as the default mode. In no-cable mode the user is able to program the desired protocol with an external controller connected to the 40-pin header. The default mode settings are shown in Tables 1, 2, and 3. By default the SMA connectors (J3, J4, and J5) are terminated with 50I and the control-transmitter input lines are all connected low.

Configuration The following provides a step-by-step procedure to aid in configuring the EV kit. The EV kit is extremely flexible and has several settings for both the ICs as well as the board. The logic signals have all been routed to the 40-pin header (J1) on the left side of the board. The protocol signals have all been routed to the female DB25 connector (J2) on the right side of the board. The chipset protocol modes can be configured to support V.28 (RS-232), V.11 (RS-449/V.36, EIA-530, EIA-530A, and X.21), and V.35 protocols. All chipset logic inputs, LED power, and shield ground connection are jumper selectable. The board includes SMA connectors (J3, J4, and J5) with optional 50I termination. The board settings are separated in the following sections: chipset protocol modes, clock/data transmitter input settings, control transmitter input settings, SMA termination, and power/ground. pin-strapped to a known state using Tables 7 and 8. INVERT defaults to logic-low. 3) Clock/data transmitter input settings: Connect the clock/data jumpers to the corresponding state using Table 9. Force the inputs of all unused transmitters low so their corresponding LED indicators are off. 4) Control transmitter input settings: Connect the control jumpers to the corresponding state using Table 10. Force the inputs of all unused transmitters low so their corresponding LED indicators are off. 5) SMA termination: 1) Connect a single 5V ±5% power supply between the VCC and GND pads located in the lower-left corner of the EV kit board. Connect the termination jumpers, depending on whether the signal source needs to be terminated with 50I, to the corresponding state using Table 11. Leave unused transmitter input lines terminated so the line is pulled down to a known state. When using SMA termination, avoid connecting JU1, JU2, and JU3 to VCC. 2) Chipset protocol modes: 6) Power/ground: View the desired chipset protocol modes in Tables 4, 5, and 6. Connect the jumpers to the corresponding state depending on whether the mode lines are controlled by an external controller or are Connect the power and ground jumpers according to the desired operation using Table 12. Leave JU17 unconnected (open) when measuring the supply current of the chipset. _______________________________________________________________________________________   5 Evaluates: MAX13170E/MAX13172E/MAX13174E Table 6.
