18QHTF21-102.400-PD

Overview

The 18QHTF21-102.400-PD is a crystal oscillator manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a frequency of 102.4 MHz with LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby (power down) function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm.

Feature Summary

• Integrated standby control for power management
• LVCMOS output signal compatibility
• Compact surface-mount footprint

Applications

• High-speed digital data transmission systems
• Communication equipment clock sources
• Network interface timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD package dimensions fit within the designated PCB area constraints.

Selection Notes

Select this component when a precise 102.4 MHz reference is required for LVCMOS-compatible circuits. The low-profile 2.0x1.6mm package suits space-constrained designs. Consider the 1.8V operating voltage to ensure compatibility with modern low-power logic families.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers standard XO configurations with various frequency options. The suffix PD indicates the inclusion of a power-down pin for energy efficiency.

Replacement Considerations

Direct replacements must match the 102.4 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications with alternative manufacturers.
