8T49N1012-007NLGI

Overview

The 8T49N1012-007NLGI is a FemtoClock NG Universal Frequency Translator manufactured by Renesas Electronics Corporation. It features one fractional-feedback PLL capable of functioning as a frequency translator with jitter attenuation or a frequency synthesizer. The device supports up to two input clocks and generates multiple output clocks, including LVPECL, LVDS, HCSL, or LVCMOS levels. It operates within a supply voltage range of 2.375V to 3.465V and is housed in a 40-VFQFN package with an exposed pad. The component is designed for high-performance timing applications requiring precise clock generation and distribution.

Procurement Notes

Verify the current lifecycle status of the 8T49N1012-007NLGI, as similar models in the 8T49N series have been discontinued. Confirm availability through authorized distributors and check for valid replacement part numbers such as the 8T49N242 series if this specific variant is no longer in production. Ensure compliance with RoHS3 specifications before procurement.

Selection Notes

Select this component when designing systems requiring flexible clock translation from various input sources (LVPECL, LVDS, etc.) to standardized outputs. Consider the 40-VFQFN package size for space-constrained PCB layouts. Verify that the required output frequencies and jitter performance meet the specific application standards, such as SyncE or SONET/SDH requirements.
