  • Page 6: Overview

    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).

  • Page 7: Modes Of Operation

    This section describes the jumpers and connectors on the EVM, as well as how to connect, set-up, and use the LMK03328EVM. When operating the LMK03328EVM, the power supply, clock inputs, and clock outputs can be connected to the SMA ports shown in Figure 2.

    Selects VDDO = 2.5 V In typical configurations, the LMK03328EVM can consume more current than USB 2.0 limit of 0.5 A. Thus, it is advised to not use the USB5V rail to power the on-board LDO regulators (i.e. do not tie pins 1-2 on JP1), unless the LMK03328 device configuration and peripheral circuitry are assured to never exceed 0.5 A current limit set by the TPS2553 USB switch (U10).
