SOIC-28 & TSSOP-28
Evaluation Board
User's Manual
Introduction
This document gives a detailed description of the
NCN8024 Evaluation Boards (SOIC−28 & TSSOP−28
versions) with the Bill Of Material (BOM), board schematic
and layout. The appropriate lab test setup is also provided.
The NCN8024 Evaluation Boards have been designed to
help for a quick evaluation of the NCN8024 Smart card
interface device.
This document has to be used with the NCN8024
datasheet. The datasheet contains full technical details

EVAL BOARD USER’S MANUAL
regarding the NCN8024 specifications and operation. The
board (FR4 material) is implemented in two metal layers.
The top and Bottom layers have thicknesses of 35 mm. The
PCB thickness is 1.6 mm with dimensions of 100 mm by
74 mm (see Figure 1).
These evaluation boards can be used to evaluate the device
performance.

Test Procedure
See Figure 2.
Initial Setups (Figure 2)
The initial setups given here are recommended before
starting measurements on the board.
Set the CMDVCC/in the OFF Position (High)
Set CLKDIV1 and CLKDIV2 into Low Position
(Lowest Frequency Fclkin)
Set 5V/3Vbar into a 5V Position
As a Precaution, Turn the 1 kW Potentiometer to Obtain
a Resistor Output Value of 1 kW, and then Connect the
Jumper
DC Power Supplies
Two power supplies are used to bias the demo board.
V
is the input voltage of the DC-DC converter. VDD is
DDP
the “digital” power supply which biases the input stages of
the NCN8024 device (control and signal inputs).

Clock Frequency
CLKDIV1 and CLKDIV2 select the frequency divider
according to the Table 2.

1 1 DIV 1/2
0 1 DIV 1/4
0 0 DIV 1/8
Card Presence
The socket we use is a normally open, so CDR-PRES/ has
been chosen; nevertheless the CRD_PRES and
CRD_PRES/ test points can also be used for signaling the
presence of a card and starting up the circuit.
Start the Measurement
To start the measurements, set the board as it follows:
Set CLKDIV1 and CLKDIV2 to Select the Correct
Frequency
Set 5V/3Vbar to Select the Correct Output Voltage
Jumpers:
1kW Potentiometer Jumper: Not Connected to Start
Measurement
Finally, Toggle/CMDVCC from High to Low to Start
the Device (Activation Sequence Run)
