Triple-Track ASIC Development PCB

1. Connect the interface signals from the J2 connector, as indicated on the PCB silkscreen,
to the customer-supplied electronics.
2. Connect the power to the J3 connector as indicated on the PCB silkscreen.
3. After power is applied, the user can then swipe a magstripe card through the reader and
monitor the signals at the J2 header. After an encoded card is swiped, the Data line will
transition low as a signal that the card has been read. At this time the customer’s interface
must begin the handshaking and data extraction routines as outlined in the Triple-Track
ASIC specifications document part number 99875259.
4. User software can then be developed to move card data from the ASIC to the user’s reader or
terminal PCB.
CONNECTORS, COMPONENTS, AND TEST POINTS
Connectors, Components, and Test Points are shown in Figure 2.
Connectors and Test Points
Mating connectors for J2 and J3 can be any 0.10” center connector such as the Molex 2695
series.
J1 connects the signals from the magstripe reader to the Triple-Track ASIC.
J2 connects power, (+2.7 – 5.5 VDC (TP1) and Gnd from an external source to the Triple-Track
ASIC Development PCB.
J3 connects DATA (TP3), which is the only output of the ASIC, STROBE (TP4), which is the
handshaking and data extraction input of the ASIC, and GND (TP2) signals to customer
interface.
Components
The magstripe read head sends signals to J1, which are then sent to U1, the Triple-Track ASIC,
for processing, and are then sent to the test points and output connector J2.
Test Points
The test points are shown and silk-screened as shown in Figure 2.
