8N4S273AC-1054CDI

Programmable Timers And Oscillators Overview

The Renesas IDT8N4S273AC-1054CDI is a factory frequency-programmable crystal oscillator utilizing FemtoClock NG technology. It provides a single LVDS differential clock output with frequencies ranging from 15.476MHz to 866.67MHz and 975MHz to 1,300MHz. The device supports 2.5V or 3.3V supplies and operates within -40°C to 85°C. Key electrical parameters include an initial accuracy of ±10 ppm, temperature stability options of ±100/±50/±20 ppm, and RMS phase jitter as low as 0.232ps (integer PLL) at 231.25MHz. It features a 6-lead ceramic package.

Programmable Timers And Oscillators Procurement Notes

Verify the specific default frequency configuration associated with the '1054' suffix against the FemtoClock NG Ceramic-Package XO and VCXO Ordering Product Information document. Confirm that the 'A' option code matches the required supply voltage (3.3V) and frequency stability specification (±100ppm) for the target application environment.

Programmable Timers And Oscillators Selection Notes

Select this component when precise, fixed-frequency LVDS clocking is required without external programming interfaces. Ensure the system power supply aligns with the 'A' suffix requirement of 3.3V ±5%. Verify that the required frequency falls within the supported ranges (15.476–866.67MHz or 975–1,300MHz) and that the thermal design accommodates the junction temperature limits given the 49.4°C/W thermal resistance.

Programmable Timers And Oscillators Part Context

This part belongs to the IDT8N4S273 family of FemtoClock NG oscillators. It is manufactured by Integrated Device Technology, Inc., which was acquired by Renesas Electronics Corporation. The device is designed for high-performance timing applications requiring low phase noise and flexible frequency synthesis via internal fractional PLL configurations.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes must match the 6-lead ceramic package, LVDS output, and specific frequency/stability requirements. Check the FemtoClock NG ordering guide for equivalent order codes with different stability options (e.g., E/F for ±50ppm) if the ±100ppm tolerance allows.
