Overview
The 18QHTF21-104.2452-PD is a 104.2452 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It utilizes LVCMOS output logic and operates on a 1.8V supply voltage. The device features a Standby function for power down control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The unit supports an operating temperature range of -40°C to 85°C and maintains frequency stability of ±50ppm.
Feature Summary
- Supports LVCMOS output logic for standard digital interface compatibility
- Includes Standby function enabling power down capability
- Compact 4-SMD No Lead surface mount package design
Applications
- General clock signal generation in electronic circuits
- Digital systems requiring precise timing references
- Embedded devices utilizing LVCMOS interfaces
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD No Lead footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when a low-profile surface mount oscillator is required for space-constrained designs. Consider the ±50ppm stability specification for applications needing moderate precision. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. Evaluate the thermal performance within the specified -40°C to 85°C range for your environmental conditions.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and package options. Mercury Electronic Ind. Co., Ltd. is a manufacturer specializing in frequency control products. The company has a history of producing quartz crystals and related components.
Replacement Considerations
Direct substitutes must match the 104.2452 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD No Lead package. Verify pinout compatibility and electrical specifications such as jitter and phase noise. Consult manufacturer cross-reference lists for approved alternatives.
