8N4SV76LC-0181CDI

Programmable Timers And Oscillators Overview

The Renesas Electronics 8N4SV76LC-0181CDI is a factory-programmable LVDS Frequency-Programmable VCXO utilizing FemtoClock® NG technology. It operates on a single 2.5V or 3.3V supply and features a lead-free (RoHS 6) 6-lead ceramic package measuring 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 or better. Key electrical parameters include an RMS phase jitter of 0.53ps typical at 156.25MHz (12kHz - 20MHz), a supply current of 140mA at 3.3V, and an operating temperature range of -40°C to 85°C.

Programmable Timers And Oscillators Feature Summary

• Factory-programmable absolute pull-range (APR) from ±4.5 to ±754.5ppm
• Single differential LVDS clock output pair (Q, nQ)
• Output enable control input compatible with LVCMOS/LVTTL levels

Programmable Timers And Oscillators Applications

• Wireless infrastructure equipment
• Telecommunication systems
• Networking end equipment

Programmable Timers And Oscillators Procurement Notes

Verify the specific default frequency and pull-range configuration programmed by the manufacturer, as these are fixed at the time of order. Confirm the option code suffix matches the required supply voltage (2.5V or 3.3V) and frequency stability accuracy. Ensure the ordering suffix corresponds to the industrial temperature range (-40°C to 85°C) and the tape & reel shipping package format if applicable.

Programmable Timers And Oscillators Selection Notes

Select this component when a low-jitter, programmable VCXO with LVDS outputs is required for space-constrained designs. The 6-lead ceramic package offers a compact footprint suitable for dense PCB layouts. Consider the internal 114.285MHz reference crystal and fractional feedback divider capabilities for precise frequency synthesis needs within the specified ranges.

Programmable Timers And Oscillators Part Context

This part belongs to the IDT FemtoClock® NG family, now under Renesas Electronics. The 'LC' in the model number indicates a 2.5V supply option and LVDS output type, while 'CDI' denotes the industrial temperature range and ceramic package. These devices are designed to replace standard oscillators where frequency agility and tight phase noise performance are critical.

Programmable Timers And Oscillators Replacement Considerations

Direct pin-to-pin replacements within the same FemtoClock NG series may exist with different option codes for varying supply voltages or stability grades. Verify that any substitute maintains the 6-lead ceramic package dimensions and LVDS output interface. Cross-reference the specific factory-programmed frequency and pull-range requirements to ensure functional equivalence.
