18QHTF21-76.000-PD

Overview

The 18QHTF21-76.000-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 76.000 MHz with an LVCMOS output logic type. The device supports a supply voltage of 1.8V and includes 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 standard clock applications requiring precise timing signals.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Includes standby and power-down functionality to reduce power consumption
• Utilizes quartz crystal technology for stable frequency generation

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's current documentation to ensure correct packaging and handling specifications. Confirm that the 1.8V supply requirement aligns with your system design before procurement. Cross-reference the part number 18QHTF21-76.000-PD with official Mercury Electronics datasheets to validate the 76.000 MHz frequency and LVCMOS output characteristics.

Selection Notes

Select this component when a low-profile 2.0x1.6mm footprint is required for space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital systems. Ensure the LVCMOS output swing matches the input requirements of the downstream logic devices. Consider the power-down feature if battery life or thermal management is a critical design constraint.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within the standard range, packaged in small SMD formats. The 'PD' suffix indicates specific packaging or handling attributes defined by the manufacturer. These oscillators are part of Mercury's broader portfolio of quartz-based timing solutions.

Replacement Considerations

Direct substitutes must match the 76.000 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical parameters such as load capacitance and drive level. Check for equivalent standby functionality and temperature stability ratings from other manufacturers offering similar SMD oscillators.
