Overview
The LMK62A2-200M00SIAT is a high-performance, low-jitter oscillator produced by Texas Instruments. This device is part of the LMK62XX series, which is designed to generate commonly used reference clock frequencies. The oscillator is pre-programmed in the factory to support various reference clock frequencies and offers output formats such as LVPECL, LVDS, and HCSL up to 400 MHz. It operates from a single 3.3-V ±5% supply and features internal power conditioning that provides excellent power supply ripple rejection (PSRR), thereby reducing the complexity and cost of the power delivery network. The device is suitable for applications requiring high stability and low noise, and it operates within an industrial temperature range of –40°C to +85°C.
