8V49NS1412NLGI8

Overview

The 8V49NS1412NLGI8 is a clock generator from the Renesas 8V49NS0312 series, designed for high-performance timing applications. It features twelve outputs with a maximum output frequency of 2.5 GHz and supports a maximum input frequency of 50 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V and consumes approximately 73 mA of operating current. It exhibits low jitter performance, specified at 87 fs, and functions reliably across an ambient temperature range of -40 °C to +85 °C. The component is housed in a VFQFN-64 package suitable for surface mount technology.

Feature Summary

• Generates up to twelve distinct output frequencies from two clock inputs and a crystal input
• Integrates three internal dividers for flexible frequency synthesis
• Supports multiple output interface standards including LVDS, LVPECL, and HCSL

Applications

• High-speed data communication systems requiring precise clock distribution
• Networking equipment utilizing multi-gigabit serial links
• Server and storage infrastructure demanding low-jitter clock signals

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with required output formats and boot modes. Confirm that the selected variant matches the intended power supply voltage and I2C address settings. Check for any recent product change notifications regarding assembly sites or material composition updates before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring twelve synchronized outputs derived from a single reference source. Ensure the design accommodates the VFQFN-64 thermal requirements and the specified 3.3 V nominal supply voltage. Validate that the target application's jitter budget aligns with the device's 87 fs specification under the expected operating conditions.

Part Context

This part belongs to the FemtoClock NG family of clock generators, which are engineered for ultra-low phase noise and jitter attenuation. The 8V49NS series specifically targets complex timing architectures where multiple clock domains must be derived from a common source with minimal skew and high stability.
