Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'A' against official Renesas documentation, as standard listings typically reference MK2049-45SILFTR or MK2049-45SITR. Confirm current availability status, as related MK2049 series devices have been subject to End-of-Life notices. Ensure compatibility with existing 20-SOIC footprints and 3.3V logic levels during integration planning.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed-ratio PLL synthesizer is required for generating T1, E1, or OC3 submultiples from an 8kHz reference. Verify that the 51.84MHz maximum output frequency meets system requirements. Consider the 20-SOIC package constraints and -40°C to 85°C operating temperature range for environmental suitability.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MK2049-45 is part of the broader MK2049 family of communications clock synthesizers. This series allows for the generation of precise clock frequencies locked to an 8 kHz backplane clock, simplifying synchronization in telecommunications infrastructure. The device integrates jitter attenuation buffer capabilities for filtering noisy input clocks.
