Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix VFEL against official Motorola or NXP documentation to confirm package type and temperature rating. Ensure compatibility with existing board layouts and supply voltage requirements before procurement. Check for end-of-life status or recommended new design alternatives if applicable.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a high-frequency PLL synthesizer with low power consumption is required. Consider the 1.1 GHz maximum operating frequency and the need for SPI-compatible control interfaces. Evaluate the dual-modulus division capabilities against the desired frequency resolution and switching speed requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MC145xxx series of PLL frequency synthesizers from Motorola. It shares functional similarities with the MC145193 but may offer updated features such as reduced power consumption and enhanced serial interface capabilities. It is designed for applications requiring reliable frequency synthesis in compact form factors.

Drivers, Receivers, Transceivers Replacement Considerations

The MC145193 is a documented alternative within the same product family. Verify pinout compatibility and register programming differences before substitution. Ensure that the replacement meets the specific frequency and power requirements of the original design.
