8T49N205A-003NLGI8

Overview

The 8T49N205A-003NLGI8 is a FemtoClock NG Universal Frequency Translator manufactured by Renesas Electronics. It features a single fractional-feedback PLL capable of functioning as a frequency translator with jitter attenuation or a frequency synthesizer. The device supports up to four integer output dividers, enabling the generation of distinct output frequencies ranging from 8kHz to 1.0GHz in differential formats or up to 250MHz in LVCMOS. It accepts multiple input clock sources and allows for auto/manual selection with hitless switching capabilities.

Feature Summary

• Supports up to four independent output frequencies generated via integer output dividers
• Features phase-slope limiting and fully hitless switching options to control output phase transients
• Includes clock input monitoring functionality with support for gapped clocks
• Configurable through I2C interface or external I2C EEPROM

Applications

• SONET/SDH network line cards
• Ethernet network line cards
• Wireless base station baseband units
• Carrier Ethernet switches

Procurement Notes

Verify the specific suffix '003NLGI8' against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm current availability status as product lifecycles may change. Ensure compatibility with required supply voltages and I2C addressing configurations before procurement.

Selection Notes

Select this component when a single PLL solution is sufficient for generating up to four distinct output frequencies. It is suitable for applications requiring jitter attenuation or synthesis from various input references. Consider alternative family members if more than four independent PLLs or different output count requirements are necessary.

Part Context

This part belongs to the FemtoClock NG Universal Frequency Translator series. These devices are designed for networking and communication equipment, offering flexible clock generation and translation. The series includes variants with varying numbers of PLLs and output configurations to suit diverse timing requirements.

Replacement Considerations
