8T49N445-000ASGI

Overview

The 8T49N445-000ASGI is a quad Universal Frequency Translator (UFT) from the FemtoClock NG family, manufactured by Renesas Electronics Corporation. It integrates four independent Phase-Locked Loops (PLLs) for frequency translation and jitter attenuation within a single package. The device supports input frequencies ranging from 8 kHz to 710 MHz and generates output frequencies between 0.98 MHz and 1300 MHz. It accepts various differential input types including LVPECL, LVDS, LVHSTL, and HCSL, with LVPECL and LVDS output signaling options. Operating on a 2.5V supply, it features low phase jitter performance of 465 fs RMS (typical) in Low Bandwidth mode and 333 fs RMS (typical) in Synthesizer mode.

Feature Summary

• Quad PLL architecture with fully independent loops supporting Frequency Synthesizer and High/Low-Bandwidth Frequency Translator modes
• Wide input frequency range of 8 kHz to 710 MHz with support for multiple differential input standards
• Output frequency capability up to 1300 MHz with selectable LVPECL or LVDS signaling
• Integrated alarm and monitoring functions suitable for networking and communications applications

Applications

• Networking equipment requiring precise clock distribution
• Telecommunications infrastructure systems
• High-speed data acquisition systems
