18QHTF21-10.625-PD

Overview

The 18QHTF21-10.625-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.625 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and supports a standby or power-down mode. It is housed in a 4-SMD, no lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports standby and power-down modes for energy management
• Utilizes LVCMOS output logic for digital interface compatibility
• Compact surface-mount design suitable for space-constrained applications

Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix and frequency tolerance against project requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout. Check for any specific handling instructions related to the crystal oscillator technology.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The compact 2.0x1.6mm package makes it suitable for dense layouts. Consider the availability of standby functionality if power efficiency during idle states is a priority for the application design.

Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within small SMD packages. The 'PD' suffix likely indicates specific packaging or tape-and-reel configuration details provided by the manufacturer.

Replacement Considerations

Direct substitutes must match the 10.625 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications before substitution.
