25QHTF22-20.900-PD

Oscillators Overview

The 25QHTF22-20.900-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 20.9 MHz and utilizes an LVCMOS output signal format. The device is designed for a supply voltage of 2.5V and features a Standby (Power Down) control function to manage power consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output interface for digital logic compatibility
• Includes standby mode capability for power management via control input
• Utilizes a leadless surface-mount package design for automated assembly

Oscillators Applications

• General-purpose clock generation in embedded systems
• Timing reference sources for microcontrollers and processors
• Data communication interfaces requiring stable frequency standards

Oscillators Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct pinout and electrical characteristics. Confirm that the 2.5V supply requirement aligns with the target system's power rails. Ensure the LVCMOS output swing is compatible with the receiving logic inputs. Check for any RoHS or REACH compliance declarations required for the procurement region.

Oscillators Selection Notes

Select this component when a 20.9 MHz frequency is specifically required for system timing. Consider the 2.5V operating voltage constraint during power budget analysis. Evaluate the 4-SMD no-lead package dimensions against available PCB real estate. Verify that the LVCMOS output level meets the noise margin requirements of the connected digital components.

Oscillators Part Context

This part belongs to the 25QHTF22 series of standard oscillators from Mercury Electronics. The series offers various frequencies within a small form factor. Mercury Electronic has extensive experience in quartz crystal manufacturing, providing frequency control products including oscillators and resonators for industrial and commercial applications.

Oscillators Replacement Considerations

Direct substitutes must match the 20.9 MHz frequency, 2.5V supply, LVCMOS output, and 4-SMD no-lead package. Verify pin configuration compatibility before substitution. Alternative parts from other manufacturers may require schematic adjustments if output voltage levels differ.
