18QHTF21-10.0013-PD

Overview

The 18QHTF21-10.0013-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.0013 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and supports a standby or power-down mode for energy management. It is housed in a compact 4-SMD, No Lead surface-mount package with dimensions of 2.0 x 1.6 mm. The component ensures frequency stability of ±50ppm and functions within an operating temperature range of -40°C to 85°C, with a maximum supply current of 24mA.

Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Includes standby and power-down functionality for reduced power consumption
• Designed for surface-mount assembly in small form-factor applications

Applications

• Digital signal processing systems requiring precise timing references
• Communication equipment utilizing standard clock frequencies
• Embedded control units needing compact oscillator solutions

Procurement Notes

Verify the specific ordering suffix 'PD' against official Mercury Electronics documentation to confirm the exact pinout and packaging configuration. Ensure that the required frequency tolerance of ±50ppm aligns with system timing requirements. Confirm that the 1.8V supply voltage matches the target circuit design before procurement. Cross-reference the 4-SMD no-lead package dimensions with PCB layout constraints to ensure proper footprint compatibility.

Selection Notes

Select this component when a 10.0013 MHz reference is strictly required for LVCMOS interfaces. Consider the ±50ppm stability specification against the application's jitter and drift tolerances. Evaluate the -40°C to 85°C industrial temperature range against environmental conditions. Compare the 24mA maximum current draw with available power budgets. Ensure the 1.8V supply rail is stable and regulated to maintain oscillator performance.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequency options within a standardized 2.0 x 1.6 mm package. These oscillators are designed for general-purpose timing applications where space efficiency and low voltage operation are prioritized over ultra-high precision or extreme temperature ranges.

Replacement Considerations

Direct substitutes must match the 10.0013 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent stability and temperature specifications from alternative manufacturers.
