18QHTF21-10.964705-PD

Overview

The 18QHTF21-10.964705-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.964705 MHz with LVCMOS output logic. The device supports a supply voltage of 1.8V and features a standby (power down) function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode to reduce power consumption
• Compact surface-mount package design

Applications

• Low-power embedded systems
• Digital signal processing circuits
• Communication modules requiring precise timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required for your manufacturing standards.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific frequency near 10.96 MHz. The LVCMOS output is suitable for standard digital logic families. Consider the standby feature if power efficiency during idle states is a priority. Verify that the small form factor fits within the available space on the printed circuit board.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down or standby control pin. These oscillators are designed for applications requiring stable clock signals in space-constrained environments.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinouts and electrical characteristics but different frequencies, such as 18QHTF21-10.000-PD. Cross-reference with other manufacturers offering 2.0x1.6mm LVCMOS oscillators operating at 1.8V, ensuring frequency and output logic match.
