Procurement Notes
This component is officially discontinued and no longer in active production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer supply. Buyers must confirm the authenticity of existing stock due to the end-of-life status.
Selection Notes
Designers seeking this specific configuration should evaluate newer generations within the FemtoClock NG portfolio. Alternative devices may offer updated features and continued manufacturing support. Reviewing the latest order guides is recommended to identify suitable replacements that maintain compatibility with existing system requirements.
Part Context
The 8T49N287 belongs to the FemtoClock NG line, which integrates advanced jitter attenuation and frequency translation capabilities. These devices are engineered for demanding telecommunications environments where signal integrity and phase noise performance are critical for maintaining network stability.
Replacement Considerations
Public documentation lists similar alternatives such as the 8T49N241-994NLGI and 8T49N242-998NLGI8. Engineers should verify pinout and electrical parameter compatibility before substituting these parts into existing designs.
