EK1HMC7044LP10B Evaluation Kit User Guide for HMC7044 Clock Jitter Cleaner
A user guide for the EK1HMC7044LP10B evaluation kit to evaluate the HMC7044 dual loop clock jitter cleaner with an integrated 122.88 MHz VCXO.
Overview
This user guide (UG-826) provides hardware and software setup instructions for the EK1HMC7044LP10B evaluation board. The kit is designed to evaluate the HMC7044, a high-performance dual-loop clock jitter cleaner suited for multicarrier GSM and LTE base station designs. The board includes a 122.88 MHz VCXO, SMA connectors for two reference inputs and six clock outputs, and an on-board PLL loop filter. The document details power management via USB or external 5V LDO regulators, signal connections for clocking, and the operation of the Windows-based graphical user interface for controlling PLL parameters, GPIOs, and output channel configurations.
Use Cases
- Evaluating clock jitter attenuation performance
- Prototyping LTE and GSM base station clock trees
- Configuring dual-loop PLL settings for low phase noise clock generation
- Testing high-frequency clock distribution for data converter sample inputs
