8N3Q001FG-1114CDI

Overview

The 8N3Q001FG-1114CDI is a programmable clock generator manufactured by Renesas Electronics. It belongs to the FemtoClock series, designed for low-jitter clock synthesis and distribution in high-speed digital systems. The device integrates multiple voltage-controlled oscillators (VCOs) and phase-locked loops (PLLs) to generate precise output frequencies from a single reference input. Key electrical characteristics include support for various output formats such as LVDS, HSTL, and SSTL, with configurable drive strengths and termination options. The component operates within a specified supply voltage range and supports I2C configuration interfaces for flexible frequency planning.

Feature Summary

• Integrated multi-VCO architecture for independent frequency generation
• Supports LVDS, HSTL, and SSTL output standards
• I2C-compatible serial interface for register programming
• Low jitter performance optimized for high-speed data transmission

Applications

• High-speed networking equipment
• Server and storage system clocking
• Telecommunications infrastructure
• Test and measurement instruments

Procurement Notes

Verify current availability status directly with authorized distributors or Renesas sales representatives, as lead times may vary. Confirm package type and tape/reel specifications match design requirements. Ensure compliance with RoHS directives if applicable to your region. Request latest datasheet revision to confirm pinout and electrical parameters before finalizing procurement.

Selection Notes

Select this component when low jitter and flexible frequency synthesis are required for high-speed interfaces. Compare output count and supported standards against system needs. Verify input reference frequency compatibility. Consider power consumption and thermal management requirements for the target application environment.

Part Context

This part is part of Renesas' FemtoClock family, which focuses on minimizing phase noise and jitter for demanding digital applications. It succeeds earlier IDT clock generator models under the Renesas brand portfolio following corporate acquisitions. The 8N3Q001FG variant specifically denotes its packaging and temperature grade within the broader product line.

Replacement Considerations

Check for direct cross-reference part numbers from Renesas or IDT legacy lists. Verify functional equivalence in terms of pinout, register map, and electrical specs. Consider newer generations like RC3xxx series for improved performance or availability.
