874002AGLF

Overview

The 874002AGLF is a high-performance differential-to-LVDS jitter attenuator manufactured by Renesas Electronics Corporation. Designed for PCI Express systems, it utilizes FemtoClock PLL technology to reduce phase noise and jitter from clock sources. The device accepts differential inputs such as LVPECL or LVDS and provides low-jitter LVDS outputs. It supports spread-spectrum clocking with a 3MHz PLL loop bandwidth, operating on a single 3.3V supply within an ambient temperature range of -40°C to 85°C. This component is intended for applications requiring precise clock signal conditioning in space-constrained environments.
