18QHTF21-10.0503-PD

Overview

The 18QHTF21-10.0503-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.0503 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Features a standby mode to reduce power consumption during inactive periods
• Utilizes a small form factor SMD package suitable for space-constrained designs

Applications

• General clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring compact oscillators

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to prevent signal integrity issues.

Selection Notes

Select this component when a precise 10.0503 MHz timing source is required in a minimal footprint. Consider the 1.8V operating voltage and LVCMOS interface compatibility with your target microcontroller or FPGA. Evaluate the need for power-down functionality if energy efficiency is a critical design constraint.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile surface-mount oscillators. The series typically offers various frequencies within a standardized 2.0x1.6 mm package, providing designers with flexible options for different clocking needs while maintaining consistent physical dimensions.

Replacement Considerations

Direct substitutes must match the 10.0503 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical specifications such as phase noise and jitter before swapping with other manufacturers' components.
