Product Introduction

Overview

The LMK61E2-SIAR from Texas Instruments is an ultra-low jitter PLLatinum programmable oscillator designed for high-performance applications. It features a fractional-N frequency synthesizer with an integrated VCO, generating commonly used reference clocks. The device is factory-programmed to produce a 156.25-MHz LVPECL output and can be configured to output LVPECL, LVDS, or HCSL signals. It operates from a single 3.3-V supply and supports industrial temperature ranges from –40°C to +85°C. The LMK61E2-SIAR is notable for its ultra-low noise and high performance, making it suitable for a variety of demanding applications.
