18QHTF22-1.415-PD

Oscillators Overview

The 18QHTF22-1.415-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 1.415 MHz and utilizes LVCMOS output logic levels. The device is designed for low power consumption, featuring a supply voltage of 1.8V and a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated standby mode for power management
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• Industrial control systems
• Consumer electronics timing circuits
• Communication equipment clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 1.8V supply voltage aligns with the system's power rails. Confirm that the 4-SMD no-lead package footprint matches the PCB layout specifications to ensure proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-frequency, low-voltage oscillator is required for space-constrained designs. The LVCMOS output is ideal for direct interfacing with microcontrollers or FPGAs operating at 1.8V logic levels. Consider the standby feature if power efficiency is critical. Verify that the 1.415 MHz frequency meets the specific baud rate or clock division needs of the application without requiring external dividers.

Oscillators Part Context

This part belongs to the 18QHTF22 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies and voltage options, all sharing the same 4-SMD no-lead form factor. The 'PD' suffix typically indicates a specific pinout or packaging variant within the manufacturer's catalog, distinct from other suffixes like 'OE' which may imply different electrical characteristics or lead-free status variations.

Oscillators Replacement Considerations

Direct replacements include other 1.415 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Epson, SiTime, or TXC. Ensure the replacement maintains the 1.8V supply requirement and compatible output drive strength. Verify that the pinout configuration is identical to avoid PCB redesign. Cross-reference with Mercury's own variants like the 18QHTF22-1.415-OE if available.
