8N4S270KC-1080CDI8

Programmable Timers And Oscillators Overview

The 8N4S270KC-1080CDI8 is a factory-programmable LVDS frequency-programmable crystal oscillator from the Renesas FemtoClock NG series. It utilizes fourth-generation technology to deliver high clock frequencies with low phase noise, specifically achieving typical RMS jitter of 0.5ps at 231.25MHz (12kHz–20MHz) and 0.6ps (1kHz–40MHz). The device supports 2.5V or 3.3V supplies and operates within an ambient temperature range of -40°C to 85°C. It is housed in a lead-free RoHS-compliant 6-lead ceramic package measuring 5mm x 7mm x 1.55mm.

Programmable Timers And Oscillators Feature Summary

• Factory-programmable output frequency ranging from 15.476MHz to 866.67MHz and 975MHz to 1,300MHz with 218Hz resolution.
• Low phase noise performance with 0.5ps typical RMS jitter (12kHz–20MHz offset).
• Single 2.5V or 3.3V LVDS clock output with positive polarity enable control compatible with LVC/LVTTL.

Programmable Timers And Oscillators Applications

• Wireless infrastructure equipment
• Telecommunication systems
• Networking end equipment

Programmable Timers And Oscillators Procurement Notes

Verify component status as this part number may be discontinued or subject to limited supply. Confirm final electrical parameters against the official datasheet before integration. Ensure compatibility with existing PCB footprints for the 6-lead ceramic package.

Programmable Timers And Oscillators Selection Notes

Select this component when precise factory-programmed frequencies are required without on-board programming overhead. The narrow jitter profile suits high-speed serial data links. Verify that the fixed output frequency matches the target system requirement, as post-manufacturing adjustment is not supported.

Programmable Timers And Oscillators Part Context

This model belongs to the 8N4S270 family of FemtoClock NG oscillators. Variants within this series differ primarily by their specific factory-programmed output frequencies and suffix codes indicating packaging or temperature grades. The KC-1080 designation identifies the specific frequency configuration for this unit.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes include other 8N4S270 variants with matching frequency specifications. Cross-reference with IDT-branded equivalents if sourcing from legacy inventories. Ensure replacement parts maintain the same 6-lead ceramic package dimensions and voltage requirements.
