18QHTF21-37.211652-PD

Oscillators Overview

The 18QHTF21-37.211652-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 37.211652 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is designed for applications requiring precise clock signals in low-profile electronic systems.

Oscillators Feature Summary

• Supports standby mode for power reduction
• Compact surface-mount package design
• LVCMOS output interface compatibility

Oscillators Applications

• Portable consumer electronics

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply rail is stable and within the specified operating range to maintain signal integrity. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions exactly to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Select this model when a low-voltage 1.8V operation is required alongside a small form factor. The LVCMOS output ensures compatibility with standard digital logic families. Consider the standby feature if power efficiency is critical for battery-operated devices. Validate that the 37.211652 MHz frequency aligns with the system clock requirements without needing additional dividers or multipliers.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The manufacturer has decades of experience in producing crystals and oscillators. The 'PD' suffix typically indicates the inclusion of a power-down pin or functionality, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 37.211652 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility for the power-down function. Cross-reference with other manufacturers offering similar SMD oscillators with identical electrical characteristics and mechanical dimensions.
