18QHTF21-57.710333-OE

Overview

The 18QHTF21-57.710333-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a precise frequency of 57.710333 MHz and utilizes LVCMOS output logic. The component is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The device is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, suitable for surface-mount assembly in space-constrained electronic designs.

Feature Summary

• Provides stable frequency reference via LVCMOS output
• Supports active low-power mode through enable/disable control
• Compact surface-mount footprint for high-density PCB layouts

Applications

• Precision timing circuits requiring 57.710333 MHz reference
• Low-voltage digital systems utilizing 1.8V logic levels
• Embedded devices necessitating compact oscillator solutions

Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's current documentation to ensure compatibility with required lead-free or environmental standards. Confirm that the 1.8V supply voltage aligns with the target system design before procurement. Cross-reference the 4-SMD package dimensions with PCB footprints to guarantee mechanical fit. Ensure the LVCMOS output swing matches the receiving input thresholds of the connected components.

Selection Notes

Select this component when a fixed frequency of 57.710333 MHz is required within a 1.8V operational environment. The choice is driven by the need for a small 2.0x1.6mm form factor and the necessity for an enable/disable pin to manage system power states. Consider the LVCMOS output type for direct interfacing with standard digital logic families without additional level shifting.

Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics, which are characterized by their small size and low voltage operation. The series typically offers various frequencies and supply voltages, with the 18 prefix indicating the 1.8V variant. These oscillators are engineered for consumer electronics and portable devices where space and power efficiency are critical constraints.

Replacement Considerations

Direct substitutes include other 57.710333 MHz XO models from Mercury Electronics with identical 1.8V supply and LVCMOS output, such as variants with different suffixes if electrical parameters match. Verify package compatibility with other manufacturers offering 2.0x1.6mm 4-SMD oscillators operating at the same frequency and voltage.
