8T49N524-005NLGI

Overview

The 8T49N524-005NLGI is a FemtoClock NG Universal Frequency Translator manufactured by Renesas Electronics Corporation. It features a single fractional-feedback PLL capable of functioning as a frequency translator with jitter attenuation or a frequency synthesizer. The device generates up to four different output frequencies ranging from 8kHz to 1GHz using integer output dividers. Outputs are configurable as LVPECL, LVDS, HCSL, or LVCMOS levels. Configuration is managed via an I2C interface or external EEPROM. The component operates within a temperature range of -40°C to +85°C and utilizes a VFQFN-56 package.

Feature Summary

• Generates up to four independent output frequencies from a single input reference using integer output dividers
• Supports flexible output signaling formats including LVPECL, LVDS, HCSL, and LVCMOS
• Configurable operation modes for jitter attenuation and frequency synthesis
• Programmable configuration via I2C interface or boot from external EEPROM

Applications

• SONET/SDH network line cards
• Ethernet network line cards
• Wireless base station baseband units
• Carrier Ethernet switches
• Test and measurement equipment

Procurement Notes

Verify the specific suffix '005' against official documentation to confirm factory pre-programmed configurations. Confirm package type and RoHS compliance status. Check for product end-of-life notices or alternative part recommendations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring precise clock generation with low phase jitter. Ensure the required output voltage levels match the available LVPECL, LVDS, HCSL, or LVCMOS options. Verify that the input clock frequencies fall within the supported operational range for the intended application mode.
