8T49N240-034NLGI

Overview

The 8T49N240-034NLGI is a low-power, high-performance clock generator from Renesas Electronics. It features four output clocks with independent frequency synthesis capabilities. The device integrates a voltage-controlled oscillator (VCO) and multiple phase-locked loops (PLLs) to generate precise timing signals. It supports I2C configuration for flexible setup. Key electrical parameters include an input clock range of 10 MHz to 200 MHz and output frequencies up to 500 MHz. The device operates at a supply voltage of 1.2V and consumes minimal power, making it suitable for portable and battery-operated applications.

Feature Summary

• Four independent output clocks with programmable frequencies
• Integrated VCO and dual PLL architecture for low jitter
• I2C interface for easy configuration and control
• Low power consumption with 1.2V supply voltage

Applications

• Portable consumer electronics requiring precise timing
• Battery-powered devices needing low power solutions
• Industrial equipment with strict clock synchronization needs
• Telecommunications infrastructure components

Procurement Notes

Verify the specific suffix '034NLGI' against official Renesas documentation to confirm pinout, package type, and operational temperature range. Ensure compatibility with existing I2C bus configurations in your design. Check for any recent revisions or obsolescence notices directly from the manufacturer before procurement.

Selection Notes

Select this component when four distinct clock outputs are required with independent frequency control. Consider its low jitter performance for sensitive analog circuits. Verify that the input clock source falls within the 10 MHz to 200 MHz range. Confirm that the 1.2V supply voltage aligns with your system's power rails.

Part Context

This part belongs to the 8T49N240 family of clock generators. It shares core architecture with other variants but differs in specific output configurations and packaging. The 'NLGI' suffix typically denotes a specific package type and temperature grade. Compare with siblings like 8T49N240-034NLG for minor functional differences.

Replacement Considerations

Direct substitutes may include other 8T49N240 variants with compatible pinouts. Verify electrical specifications such as jitter performance and supply current. Ensure the replacement supports the same I2C addressing and configuration commands. Consult Renesas for qualified alternate parts if availability is an issue.
