8N3S270KC-1102CDI

Programmable Timers And Oscillators Overview

The 8N3S270KC-1102CDI is a frequency-programmable crystal oscillator from Renesas Electronics, utilizing fourth-generation FemtoClock NG technology. It provides a single LVPECL clock output with factory-programmable frequencies ranging from 15.476MHz to 866.67MHz and 975MHz to 1,300MHz. The device operates on a 2.5V or 3.3V supply within an ambient temperature range of -40°C to 85°C. It features low phase jitter, typically 0.24ps RMS at 156.25MHz (12kHz–20MHz) and 0.23ps RMS at 240MHz (12kHz–20MHz). Packaged in a lead-free RoHS 6 compliant 6-pin ceramic package measuring 5mm x 7mm x 1.55mm, it supports high-frequency precision of 218Hz or better.

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix '1102' against official Renesas documentation to confirm the exact programmed frequency and pinout configuration. As this component belongs to the 8N3S270 series, check for potential lifecycle status updates such as discontinuation or last-time buy notices. Ensure compatibility with 2.5V or 3.3V power domains during procurement planning.

Programmable Timers And Oscillators Selection Notes

Select this oscillator when low phase jitter is critical for high-speed digital interfaces. The 8N3S270KC variant specifically offers LVPECL outputs suitable for differential signaling applications. Verify that the required frequency falls within the supported ranges of 15.476MHz–866.67MHz or 975MHz–1,300MHz. The 6-pin ceramic package requires appropriate PCB footprint design considering the 5mm x 7mm dimensions.

Programmable Timers And Oscillators Part Context

This part is a member of the 8N3S270 family of frequency-programmable crystal oscillators. It shares core FemtoClock NG technology with variants like the 8N3S270EC-1103 and 8N4S270 series. While the 8N4S270 offers LVDS outputs, the 8N3S270 series is distinguished by its LVPECL output capability. All variants share similar packaging and electrical operating conditions.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements must match the LVPECL output type and FemtoClock NG architecture. Consider the 8N3S270EC-1103 if LVPECL output is required but verify frequency programming differences. Cross-family substitution with 8N4S270 models requires level shifting due to LVDS vs LVPECL output differences.
