18QHTF21-65.010-PD

Overview

The 18QHTF21-65.010-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 65.01 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down mode capability. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component serves as a precise clock source for digital circuits requiring low-profile surface-mount integration.

Feature Summary

• LVCMOS output logic for direct interface with digital loads
• Integrated standby function to reduce power consumption
• Compact 4-SMD no-lead surface mount package design

Applications

• Portable electronic devices requiring low profile components
• Consumer electronics with strict space constraints
• Industrial control systems utilizing LVCMOS interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required frequency tolerance and load capacitance specifications. Confirm that the 1.8V supply voltage aligns with the target system design before procurement. Check for any recent updates to the RoHS compliance status or lead-free material declarations provided by Mercury Electronics.

Selection Notes

Select this oscillator when a 65.01 MHz clock signal is required within a 2.0x1.6mm footprint. Ensure the application supports LVCMOS logic levels and can provide a stable 1.8V power rail. Consider the standby feature if power management during idle states is a critical design requirement for the end product.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies in a standardized small outline package. The 'PD' suffix typically indicates specific packaging or tape-and-reel configuration details defined by the manufacturer for automated assembly processes.

Replacement Considerations

Direct replacements must match the 65.01 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter against the original specification sheet.
