1 Introduction

Overview

The LMK5B33216EVM is an evaluation module for the LMK5B33216 Network Clock Generator and Synchronizer. The EVM can be used for device evaluation, compliance testing, and system prototyping. The LMK5B33216 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 the LMK5B33216 to be evaluated in free-running, locked, or holdover mode of operation. 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 LMK5B33216 registers.
