8N4Q001FG-1164CDI8

Programmable Timers And Oscillators Overview

The Renesas 8N4Q001FG-1164CDI8 is a programmable quad-frequency voltage-controlled crystal oscillator (VCXO) belonging to the FemtoClock NG family. It utilizes fourth-generation technology to deliver high clock frequencies with low phase noise. The device supports output frequencies ranging from 15.476MHz to 866.67MHz and 975MHz to 1,300MHz, with an absolute pull range (APR) programmable from ±4.5ppm to ±754.5ppm. It features one LVDS differential clock output and operates on a single 2.5V or 3.3V supply within a -40°C to 85°C temperature range.

Programmable Timers And Oscillators Feature Summary

• Quad-frequency programmability via I2C interface with four power-up defaults selectable by FSEL pins
• Low RMS phase jitter of 0.494ps (typical) at 156.25MHz (12kHz-20MHz bandwidth)
• Wide frequency tuning range: 15.476MHz–866.67MHz and 975MHz–1,300MHz
• Programmable APR from ±4.5ppm to ±754.5ppm for precise synchronization

Programmable Timers And Oscillators Applications
