Overview
The CMX940T1-TR1K is a fractional and integer-N RF synthesizer with an integrated VCO, manufactured by CML Microcircuits. It operates within a frequency range of 49MHz to 2.04GHz and utilizes a 3V to 3.6V supply voltage. The component is housed in a 48-LGA package measuring 7x7mm. This device is designed for general-purpose radio frequency applications requiring precise frequency synthesis.
Feature Summary
- Integrates a Voltage Controlled Oscillator (VCO) directly into the synthesizer architecture
- Supports both fractional and integer-N phase-locked loop configurations
- Provides low power consumption suitable for portable wireless devices
Applications
- Wireless communication systems
- General purpose RF signal generation
- Portable electronic devices requiring frequency synthesis
Procurement Notes
Verify the specific ordering suffix TR1K to ensure the correct tape and reel quantity of 1000 units is obtained. Confirm that the 48-LGA 7x7mm package matches your PCB footprint requirements. Check the manufacturer's latest documentation for any updates regarding lead times or availability status before finalizing procurement plans.
Selection Notes
Select this component when a combined synthesizer and VCO solution is required for frequencies up to 2.04GHz. Ensure the design supports the specified 3V to 3.6V operating voltage range. Consider the 48-LGA package size constraints during layout planning. Verify compatibility with the desired modulation scheme supported by the fractional or integer-N modes.
Part Context
This part belongs to the CMX940 series of clock synthesizers and jitter cleaners from CML Microcircuits. It is engineered for high-performance RF applications where low phase noise and wide frequency coverage are critical. The integration of the VCO simplifies the overall system design by reducing external component count.
Replacement Considerations
Consult official CML Microcircuits documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully if considering alternative RF synthesizers with similar frequency ranges.
