Introduction

The MicroClock development kit is designed to support the 5x2503 family of MicroClock devices. It provides a convenient way of
verifying, configuring and programming the blank parts for all MicroClock devices. The IDT Timing Commander
the devices for configuration and frequency validation on the USB mother board via an on-board USB interface. Using additional socket
daughter boards, a validated configuration is used to program blank parts for any of the MicroClock devices.

Socket Daughter Board Overview

The MicroClock socket daughter board is ready with all of the necessary components and connections to test the functionality of the
configuration. A blank device is placed in the socket for programming (see Figure 1).

(Evaluation socket daughter board combined with a USB mother board)

The socket daughter board for 5x2503, combined with a USB mother board, is used for the purpose of validation and measurement on all
outputs. After a configuration is validated on the USB mother board, the board can be connected along with the specific socket daughter
board for programming on blank parts of MicroClock family devices. Note that blank parts can only be burnt once through the socket
daughter board. The socket daughter board is bundled with a USB mother board. The following description and images are restricted to
the socket daughter board.

On the footprint of the socket daughter board, a pin orientation identifies the position of Pin 1 as shown in Figure 3. Align the dot of the
blank part in the socket as pointed. After placing the blank part, secure the socket cover.

A configuration has been validated and
completed on the development kit.

All intended outputs should be available for
measurement on the USB development kit.

Plug the specified socket daughter board

onto the USB mother board (shown in

Figure 2).

Configurations should have been validated on the USB mother board
and are ready to proceed for programming on blank parts.

Upon validation of the outputs, “Disconnect” the USB board and
proceed for OTP burn as explained in the following sections.
