18QHTF21-100.150-PD

Overview

The 18QHTF21-100.150-PD is a 100.15 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a supply voltage of 1.8V and utilizes an LVCMOS output signal format. The component features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead surface-mount package with dimensions of 2.00mm x 1.60mm.

Feature Summary

• Supports LVCMOS output interface
• Includes standby power down functionality
• Compact 4-SMD no lead package

Applications

• General electronic circuit timing
• Embedded system clock generation
• Portable device power management

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions to prevent assembly errors during manufacturing.

Selection Notes

Select this model when a precise 100.15 MHz reference is required in space-constrained designs. The low profile and small footprint make it suitable for dense layouts. Consider the standby feature if power efficiency is critical. Verify compatibility with the host controller's input voltage levels and drive strength requirements.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The PD suffix indicates the presence of a power-down pin or control mechanism, distinguishing it from models without standby capabilities.

Replacement Considerations

Direct substitutes must match the 100.15 MHz frequency, 1.8V operation, LVCMOS output, and 4-SMD package. Check datasheets for equivalent parts from other manufacturers ensuring identical pinout and electrical characteristics.
