Overview
The LMK03328EVM evaluation module provides a complete clocking platform to evaluate the clock
performance and pin-/software-configuration modes and features of the Texas Instruments LMK03328
Ultra-Low-Jitter Clock Generator with Dual PLLs, 8 outputs, 2 inputs, and integrated EEPROM.
The LMK03328EVM can be used as a flexible, multi-output clock source for compliance testing,
performance evaluation, and initial system prototyping. The onboard edge-launch SMA ports provide
access to the LMK03328 clock inputs and outputs for interfacing to test equipment and reference boards
using commercially available coaxial cables, adapters, or baluns (not included). This connectivity enables
integrated system level testing between TI’s LMK03328 and third-party FPGA/ASIC/SoC reference
boards. A software graphical user interface (GUI) platform can be installed on a Host PC to access the
LMK03328 device registers and EEPROM via the on-board USB-to-I2C interface. The GUI platform can
also be used to export / import Register and EEPROM data files to facilitate factory or in-system
programming of custom device configurations.
