• Operates at 8 GHz base phase frequency detection capability
• Utilizes silicon technology for robust RF signal processing

Applications

• High-frequency phase-locked loop systems
• RF synthesizer design
• Microwave communication equipment

Procurement Notes

Verify the specific revision status and RoHS compliance details directly with the manufacturer or authorized distributors before procurement. Confirm that the 3.3 V supply requirement aligns with your system design. Ensure thermal management solutions are adequate for operation up to +85 C. Check for any specific ordering increments or packaging constraints defined in the official datasheet.

Selection Notes

Select the PFD1K when designing systems requiring phase frequency detection at frequencies up to 40 GHz. Ensure the application environment remains within the specified operating temperature range. Verify compatibility with the 3.3 V power supply infrastructure. Consider the integration of dual prescalers if higher frequency multiplication or division ratios are necessary for the target RF architecture.
