EVALUATION BOARD HARDWARE

POWER SUPPLY

Connector J5 supplies the VDD and GND supplies to the board.

These supplies can be selected for each pin of the device by setting

the link headers to either VDD or GND. When a VSS supply is

needed, apply the voltage directly to the VSS or GND pin of the

device by removing the corresponding link.

LINK HEADERS

The link headers supply the device under test (DUT) with either

VDD or GND. The headers are designated K1 to K14 with the

number of the header corresponding to the pin number of the

device. Table 1 summarizes the link headers and their functions

on the EVAL-14TSSOPEBZ evaluation board.

H stands for high.

L stands for low.

SMB CONNECTORS

There are four SMB connectors on the evaluation board: J1 to J4.

When an SMB cable is connected to one of these connectors, the

input signal becomes available on the corresponding P1 to P4

ports. Apply this signal to the relevant pin of the device by forming

a connection from the P1 to P4 ports to a gold pin connector

found on the relevant trace.

INPUT SIGNAL TRACES

Each trace includes three sets of gold pin connectors: two sets

that can place a load on the signal path to ground and one set

that is in series with the signal path. The three sets of gold pin

connectors can create a simple resistor capacitor (RC) filter.
