1 Introduction

Overview

The LMK5C33414AEVM is an evaluation module for the LMK5C33414AEVM Network Clock Generator and Synchronizer. The EVM can be used for device evaluation, compliance testing, and system prototyping. The LMK5C33414A integrates three Analog PLLs (APLL) and three Digital PLLs (DPLL) with programmable loop bandwidth. The EVM includes SMA connectors for clock inputs, optional off-board APLL reference input, and clock outputs to interface the device with 50-Ω test equipment. The onboard TCXO allows for improved performance when using low DPLL loop bandwidths below 10 Hz and when evaluating holdover, locked, or free-run operational modes. The EVM can be configured through the onboard USB microcontroller (MCU) interface using a PC with TI's TICS Pro software graphical user interface (GUI). TICS Pro can be used to program the LMK5C33414A registers.
