PT7C5020ALF-2GWF

Overview

The PT7C5020ALF-2GWF is a voltage-controlled oscillator (VCO) from Diodes Incorporated, designed for high-frequency applications. It operates at a center frequency of 55MHz with a typical second harmonic suppression of specified dBc levels. The component supports operation voltages ranging from 1.8V to 5.5V, accommodating both 1.8V and 2.25V system requirements. It is housed in a compact surface-mount package measuring 1.0x0.5mm, suitable for space-constrained designs.

Feature Summary

• Provides stable high-frequency oscillation centered at 55MHz
• Supports wide supply voltage range from 1.8V to 5.5V
• Features low phase noise characteristics for signal integrity
• Utilizes a miniature surface-mount footprint

Applications

• Wireless communication modules requiring precise frequency generation
• RF transceiver circuits needing local oscillator signals
• Test and measurement equipment utilizing stable clock sources

Procurement Notes

Verify the specific ordering suffix and package variant against the official datasheet before procurement. Confirm that the 1.0x0.5mm package dimensions align with your PCB layout constraints. Ensure the operating voltage range matches your system's power supply specifications. Check for any recent product change notifications regarding manufacturing updates or pinout modifications.

Selection Notes

Select this VCO when a 55MHz output is required within a minimal footprint. Consider the 1.8V to 5.5V input flexibility for compatibility with various logic families. Evaluate the thermal performance and power consumption relative to your application's battery life or cooling capabilities. Compare alternative frequencies if the exact 55MHz requirement can be adjusted.
