6V49R904-074NLGW3

Overview

The Renesas 6V49R904-074NLGW3 is a VersaClock 6 low-power programmable clock generator designed for high-performance consumer, networking, industrial, computing, and data communications applications. It features three universal outputs supporting LVPECL, LVDS, HCSL, or six LVCMOS outputs, plus an additional LVCMOS reference output. The device supports in-system programming with up to three independent output frequencies reaching 350 MHz. It stores four configurations in OTP memory and operates within a -40°C to +85°C temperature range. Key electrical characteristics include core power consumption of less than 100 mW at 3.3 V and typical RMS phase jitter of less than 0.5 ps. It meets PCIe Gen 1/2/3, USB 3.0, and 1/10 GbE clock requirements.

Feature Summary

• Three universal outputs (LVPECL/LVDS/HCSL) or six LVCMOS outputs with one additional LVCMOS reference output.
• In-system programmable with up to three independent output frequencies up to 350 MHz.
• Stores four different configurations in on-chip one-time programmable (OTP) memory.
• Low power consumption: <100 mW core power at 3.3 V; <0.5 ps RMS phase jitter.

Applications

• Ethernet switches/routers
• PCI Express systems
• High-performance consumer electronics
• Industrial computing
• Data communications

Procurement Notes

Verify the specific suffix '074NLGW3' against official Renesas documentation to confirm pinout, package dimensions, and voltage levels. Ensure compatibility with required I2C addresses and bootstrapping configurations for system integration.

Selection Notes

Select this component when glitchless manual switchover between redundant clocks is required. Consider its support for multiple I2C addresses if multiple devices are used in a single system. Verify that the 350 MHz maximum frequency meets the target application's timing requirements.

Part Context

This part belongs to the VersaClock 6 family, representing Renesas' sixth generation of programmable clock technology. It is designed to replace older fixed-frequency oscillators in complex digital systems requiring flexible clock distribution and low jitter performance.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult Renesas technical support for direct replacements or cross-references based on specific electrical and pinout requirements.
