8N4S270KG-1111CDI8

Programmable Timers And Oscillators Overview

The 8N4S270KG-1111CDI8 is a factory-programmable LVDS frequency-programmable crystal oscillator from the FemtoClock NG series by Renesas Electronics. It utilizes fourth-generation technology to deliver high clock frequencies with low phase noise, achieving typical RMS jitter of 0.5ps (12kHz–20MHz) at 231.25MHz. The device supports output frequencies from 15.476MHz to 866.67MHz and 975MHz to 1,300MHz with a resolution of 218Hz or better. It operates on a single 2.5V or 3.3V supply and features an output enable control compatible with LVCMOS/LVTTL levels.

• Networking end equipment

Programmable Timers And Oscillators Procurement Notes

Verify component authenticity through authorized distributors as counterfeit risks exist for legacy clock generators. Confirm the specific factory-programmed frequency matches the design requirements since the output is fixed at manufacture. Check RoHS compliance status and lead-free packaging specifications before integration into final assemblies.

Programmable Timers And Oscillators Selection Notes

Select this model when precise, fixed-frequency LVDS clocking is required without external programming interfaces. Ensure the target frequency falls within the supported ranges of 15.476MHz–866.67MHz or 975MHz–1,300MHz. Verify that the 0.5ps jitter specification meets the system's timing budget for high-speed data transmission applications.

Programmable Timers And Oscillators Part Context

This component belongs to the 8N4S270 series of programmable oscillators. It is part of Renesas' FemtoClock family, which succeeded earlier IDT products. The 'KG' suffix typically denotes specific package or pinout variations within the series, while 'CDI8' indicates ceramic packaging and tape-and-reel delivery format.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements may include other FemtoClock NG devices with similar jitter profiles and LVDS outputs. Verify pin compatibility and electrical parameters such as supply voltage and operating temperature range (-40°C to 85°C). Consult Renesas documentation for cross-reference lists if the original part is discontinued.
