Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific factory preprogrammed configuration associated with the numerical suffix B06182, as this part number represents a custom device rather than a blank prototype. Confirm that the tape and reel packaging option aligns with automated assembly requirements. Ensure compatibility with the I2C or SPI serial interface used for device control and status monitoring during integration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a two-output solution with high-frequency flexibility is required. The Si5342D variant specifically limits output frequencies to 350 MHz, distinguishing it from higher-speed A or C variants. Verify that the 44-QFN footprint fits the PCB layout constraints and that the 1.8 V and 3.3 V power rails are available within the system design specifications.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This device belongs to the Si5345/44/42 Rev D series, which utilizes MultiSynth and DSPLL technologies. While the Si5345 offers ten outputs and the Si5344 provides four, the Si5342 is optimized for applications requiring only two outputs. All models share identical input capabilities and core jitter performance characteristics within the same package families.
