8N4Q001EG-1014CDI8

Programmable Timers And Oscillators Overview

The Renesas 8N4Q001EG-1014CDI8 is a programmable quad-frequency voltage-controlled crystal oscillator (VCXO) belonging to the FemtoClock NG series. 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 a programming resolution of 435.9Hz ÷N. It features an I2C interface for frequency, APR, and PLL control, alongside two LVCMOS/LVTTL-compatible control inputs for selecting power-up default frequencies. The component operates on a 2.5V or 3.3V supply within a -40°C to 85°C temperature range.

Programmable Timers And Oscillators Part Context

This component is part of the IDT/Renesas 8N4Q001 family, which are quad-frequency programmable VCXOs. The specific suffix '1014' denotes the four power-up default frequencies configured at the factory. These devices are designed for applications requiring flexible frequency synthesis and precise pull-range control in demanding environments.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the 10-CLCC package and FemtoClock NG architecture. Verify that alternative parts support the same dual frequency bands (15-866 MHz and 975-1300 MHz) and I2C programmability. Ensure the substitute maintains the required APR range and jitter specifications for the target application.
