18QHTF21-2.096-PD

Oscillators Overview

The 18QHTF21-2.096-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 2.096 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a power-down (Standby) control function to reduce consumption when inactive. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for timing applications requiring low voltage operation and small form factor integration.

Oscillators Feature Summary

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

Oscillators Applications

• Low-voltage digital circuit timing
• Portable electronic devices requiring power efficiency
• Communication equipment clock sources

Oscillators Procurement Notes

Verify the specific operating temperature range and frequency stability parameters against the official datasheet before procurement, as these values are critical for system reliability. Confirm that the 1.8V supply requirement aligns with the target board's power rail capabilities. Ensure the 4-SMD footprint matches the PCB layout design rules. Check for any RoHS or REACH compliance documentation if required by local regulations.

Oscillators Selection Notes

Select this component when a 2.096 MHz clock signal is required with a 1.8V supply constraint. The LVCMOS output is suitable for direct interfacing with standard CMOS logic families. Consider the 2.0x1.6mm package size for space-constrained designs. The power-down feature is advantageous for battery-operated systems where standby current reduction is necessary. Verify that the load capacitance requirements match the connected circuitry.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies and supply voltages, typically utilizing quartz crystal technology for stable timing. The 'PD' suffix indicates the inclusion of a power-down pin or function. These components are generally used in consumer electronics, industrial controls, and telecommunications equipment where precise frequency generation is essential.

Oscillators Replacement Considerations

Direct replacements must match the 2.096 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Other Mercury parts in the 18QHTF21 series with different frequencies may be compatible if the electrical characteristics align. Cross-manufacturer substitutes require verification of pinout compatibility and electrical specifications.
