Overview
The 8V49NS4812NLGI is a clock generator from the Renesas 8V49NS0312 series, designed for high-performance timing applications. It features 12 outputs with a maximum frequency of 2.5 GHz and supports up to 50 MHz input frequencies. The device operates within a supply voltage range of 3.135 V to 3.465 V, consuming 73 mA of current. Packaged in a VFQFN-64 format, it functions reliably across an industrial temperature range of -40°C to +85°C. Key electrical specifications include a maximum duty cycle of 60% and jitter performance of 87 fs.
Feature Summary
- Generates up to 12 output clocks with a maximum frequency of 2.5 GHz
- Supports input frequencies up to 50 MHz
- Operates on a single 3.3 V power supply (3.135 V to 3.465 V)
- Industrial temperature rating from -40°C to +85°C
Applications
- High-speed networking equipment
- Telecommunications infrastructure
- Data center interconnects
Procurement Notes
Verify the specific suffix 'NLGI' against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with I2C programming interfaces and check for any regional manufacturing restrictions or RoHS compliance certificates prior to ordering.
Selection Notes
Select this component when multiple differential or single-ended outputs are required at frequencies up to 2.5 GHz. Confirm that the system design accommodates the 64-pin VFQFN footprint and that the 87 fs jitter specification meets the signal integrity requirements of the target application.
Part Context
This part belongs to the 8V49NS0312 family of clock generators. These devices are engineered for jitter attenuation and frequency synthesis in demanding digital systems. The 8V49NS4812 variant specifically provides a higher output count compared to lower-end models in the same series.
Replacement Considerations
Consult the official Renesas cross-reference guide for verified pin-compatible alternatives. Generic substitutes may not match the specific 87 fs jitter or 2.5 GHz frequency limits.
