MicroClock 5x2503 Family User Guide Development Kit 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 GUI communicates to 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. Table 1. MicroClock Family Products Product Description Package 5X2503 1.8V integrated with an internal 26M crystal. 12-DFN 5L2503 1.8V using an external 26M crystal. 12-DFN For details of product operation, refer to the product datasheet. 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). Figure 1.

Used to configure the device in different modes (software mode as default 10 DIP Switch 2 for I C control hardware mode as output pin control selection). Figure 2. Development Kit Boards (Evaluation socket daughter board combined with a USB mother board) Socket Daughter Board 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. 2017 Integrated Device Technology, Inc. 2 October 20, 2017
