18QHTF21-13.02187-PD

Overview

The 18QHTF21-13.02187-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 13.02187 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) control function to manage power consumption. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Standby mode support for power management
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific ordering suffix 'PD' corresponds to the Standby (Power Down) functionality as indicated in distributor listings. Confirm that the 1.8V supply voltage requirement aligns with the target system design. Ensure the 4-SMD no-lead footprint matches the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standby feature for power efficiency. The LVCMOS output is appropriate for standard digital logic families. Consider the 13.02187 MHz frequency specifically if it matches the required clock input for the target application, rather than using generic frequency alternatives.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. The series offers various frequencies and supply voltages. The '-PD' suffix distinguishes this variant by its power-down capability, differentiating it from variants like '-OE' which offer enable/disable controls or non-controlled outputs.

Replacement Considerations

Direct substitutes within the same series include 18QHTF21-13.02187-OE, though the latter provides Enable/Disable control instead of Standby. Other frequency variants such as 18QHTF21-51.200-PD share the same package and logic but differ in frequency.
