INTERFACING TO THE EZ-KIT LITE
The EZ-KIT LITE board must be modified by the inclusion of a right-angled male header strip (20 x 2) in positions 11 to
50 of connector P3. This header mates to a matching female connector (J11) on the AD73322 Evaluation board.
•
Connect the AD73322 EVAL BOARD to the EZ-KIT LITE BOARD using J11.
•
Plug the daughter board onto the EVAL BOARD using J1, J2, J5 and J6.
•
Connect the serial cable between PC and EZ-KIT LITE.
•
Attach the power loop through cable between J10 of the EVAL BOARD and the power input of the EZ-KIT BOARD.
•
Apply power to the setup via J9 using the DC PSU supplied with the eval board.
When power is applied the green LED on EZ-KIT BOARD should remain lit while red LED should flash to indicate system
is ready to accept a program. If any difficulty is experienced please refer to the EZ-KIT LITE REFERENCE MANUAL.
Analog I/O.
The analog I/O to each codec is designed to be flexible and the evaluation board provides some prototyping space for
user supplied input/output circuitry. Codecs 1(U1) uses a pair of stereo (3 pole) 3.5 mm miniature jack plugs (J13
through J16) to connect signals to/from the evaluation board via single-in-line sockets J12 and J2 and from the
prototyping space through J5 and J6. Codecs 2(U2) uses single-in-line sockets J3 and J4 and from the prototyping area
through J7 and J8.
