18QHTF21-13.57375-PD

Overview

The 18QHTF21-13.57375-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 13.57375 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, featuring a supply voltage of 1.8V. It includes a standby or power-down function to manage energy consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This configuration supports surface-mount assembly processes suitable for space-constrained electronic designs.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Integrates standby and power-down functionality for power management
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• Telecommunications equipment clock generation
• Consumer electronics timing circuits
• Industrial control system synchronization

Procurement Notes

Verify the specific ordering suffix PD against the manufacturer's current datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the 1.8V supply voltage aligns with the target circuit's power rails. Confirm the 4-SMD no-lead package footprint matches the PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a precise 13.57375 MHz reference signal is required for LVCMOS-compatible digital systems. The 1.8V operating voltage makes it suitable for modern low-power portable devices. Consider the small 2.0x1.6mm footprint if board space is limited. Verify that the standard XO stability specifications meet the application's jitter and accuracy requirements.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequencies within a standardized 4-SMD no-lead package. Mercury Electronics has specialized in frequency control products since 1973, establishing itself as a pioneer in the quartz crystal industry in Taiwan. The series is designed for general-purpose timing applications.

Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical 1.8V LVCMOS specifications but different frequencies, such as 18QHTF21-48.7056-PD or 18QHTF21-18.1059-PD, provided the frequency difference is acceptable for the application.
