18QHTF21-10.752-PD

Overview

The 18QHTF21-10.752-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.752 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode to reduce energy consumption during idle periods. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm, suitable for space-constrained surface-mount designs.

Feature Summary

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

Applications

• General clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Portable electronic devices requiring power management

Procurement Notes

Verify the specific ordering suffix '-PD' against the manufacturer's current documentation to ensure correct pinout and electrical specifications. Confirm that the 1.8V supply requirement aligns with your system design before procurement. Check for any recent revisions to the datasheet regarding mechanical tolerances or thermal characteristics.

Selection Notes

Select this component when a precise 10.752 MHz timing source is required with minimal power consumption. Ensure the host circuit supports LVCMOS logic levels and provides a stable 1.8V supply. Consider the small form factor if board space is limited, and verify that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 2.0x1.6mm footprint. The series is characterized by low power consumption and standard CMOS outputs, targeting consumer electronics and portable devices where size and energy efficiency are critical design constraints.

Replacement Considerations

Direct substitutes must match the 10.752 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify equivalent jitter and stability specifications from alternative manufacturers to ensure system performance remains unaffected.
