8N4SV76EC-0065CDI

Programmable Timers And Oscillators Overview

The Renesas Electronics Corporation 8N4SV76EC-0065CDI is an LVDS Frequency-Programmable VCXO utilizing FemtoClock NG technology. It operates on a 2.5V or 3.3V supply within a 6-lead ceramic package (5mm x 7mm x 1.55mm). The device supports output frequencies from 15.476MHz to 866.67MHz and 975MHz to 1,300MHz with a programming resolution of 218Hz. Key electrical parameters include a typical RMS phase jitter of 0.53ps at 156.25MHz (12kHz - 20MHz) and a power supply current of 140mA to 175mA. It features an absolute pull range programmable from ±4.5 to ±754.5ppm and operates across an ambient temperature range of -40°C to 85°C.

Programmable Timers And Oscillators Procurement Notes

Verify the specific factory-programmed default frequency and VCXO pull range associated with the '0065' suffix, as these are customized during manufacturing. Confirm the option code 'E' indicates a 3.3V supply with ±50 ppm crystal frequency accuracy. Ensure compatibility with the required LVDS termination impedance and check for any product change notices affecting the component revision.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-jitter, frequency-agile VCXO is required for systems needing precise frequency synthesis. The 8N4SV76EC variant specifically supports a 3.3V supply with ±50 ppm stability. Designers must account for the internal 114.285MHz reference crystal and ensure the application circuit provides adequate power supply filtering to maintain optimal jitter performance.

Programmable Timers And Oscillators Part Context

This part belongs to the IDT8N4SV76 family of LVDS Frequency-Programmable VCXOs manufactured by Integrated Device Technology, which was acquired by Renesas Electronics. The 'EC' designation specifies the 3.3V supply voltage and ±50 ppm stability option, while 'CDI' denotes the industrial temperature range and lead-free ceramic packaging.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements require matching the FemtoClock NG architecture, LVDS output type, and 6-lead ceramic package dimensions. Verify that alternative parts support the same frequency range (15.476MHz–866.67MHz and 975MHz–1,300MHz) and have comparable phase jitter specifications.
