Replacement Risk Around the Renesas Electronics Corporation 8N3SV76KC-0170CDI 100MHz VCXO
When a Renesas Electronics Corporation 8N3SV76KC-0170CDI VCXO is unavailable, approaching end-of-life planning, or constrained by lead time, the replacement decision is not limited to finding another 100MHz oscillator. The substitute must preserve frequency accuracy, voltage-control behavior, output compatibility, jitter performance, board footprint, supply range, enable behavior, and thermal rating. A part that matches the nominal frequency may still fail in a PLL loop, telecom timing path, FPGA reference clock input, or high-speed data converter clock tree if its electrical or mechanical details differ.

What the Renesas Electronics Corporation 8N3SV76KC-0170CDI Defines in the Original Clock Design
The Renesas Electronics Corporation 8N3SV76KC-0170CDI is a FemtoClock NG series VCXO designed for precision clock/timing applications. Its core identity is a 100MHz voltage-controlled crystal oscillator in a 6-CLCC 7mm x 5mm surface-mount package. It operates from a 3.135V to 3.465V supply, draws approximately 130mA, and supports an industrial temperature range from -40°C to +85°C. The device is RoHS3 compliant, REACH unaffected, MSL 1, and classified under ECCN EAR99.

|---|---|
| Manufacturer | Renesas Electronics Corporation |
| Series | FemtoClock NG |
| Device Type | VCXO |
| Nominal Frequency | 100MHz |
| Supply Voltage | 3.135V to 3.465V |

| Compliance | RoHS3 compliant, REACH unaffected, MSL 1 |
The supply range indicates that replacement devices should normally be selected from 3.3V oscillator families rather than 2.5V-only or 1.8V-only versions unless the board provides a separate rail or level translation. The 130mA current also suggests the original design may tolerate a relatively higher-performance clock device, but power and thermal budgets should still be checked when using lower-current MEMS or higher-current low-jitter crystal alternatives.
The 6-CLCC 7mm x 5mm package is one of the most influential replacement constraints. Many 100MHz VCXOs are available in 5mm x 7mm oscillator packages, but pinout conventions vary by manufacturer. Even when the land pattern appears similar, the control-voltage pin, output pins, enable pin, and ground placement may differ. Mechanical similarity should not be interpreted as pin-for-pin compatibility without layout verification.
Typical applications for this class of 100MHz VCXO include PLL reference clocks, Ethernet and optical networking timing, FPGA transceiver clocking, data acquisition timing, telecom timing recovery, storage systems, and synchronization circuits. In these designs, a replacement must preserve not only frequency but also control slope, tuning linearity, jitter/phase-noise behavior, startup time, output format, and environmental stability.
