Overview
The 18QHTF21-7.160-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.16 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- LVCMOS output interface for digital logic compatibility
- Integrated enable/disable pin for power control
- Surface-mount 4-SMD no-lead package design
Applications
- Digital signal processing circuits
- Communication equipment timing references
- Embedded system clock generation
Procurement Notes
Verify the specific ordering suffix to ensure the correct frequency and package variant matches the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure the enable/disable functionality is supported by the controlling microcontroller or logic circuit.
Selection Notes
Select this component when a low-voltage 1.8V operation is required for timing applications. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the small 4-SMD footprint for space-constrained PCB layouts. Verify that the 7.16 MHz frequency meets the specific clocking needs of the application without requiring additional frequency multiplication.
Part Context
Mercury Electronic Ind. Co., Ltd. is a manufacturer of frequency control products with a history dating back to 1973. The company is recognized as a pioneer in the quartz crystal industry in Taiwan. Their product portfolio includes various oscillators and crystals designed for precision timing applications across multiple electronic sectors.
Replacement Considerations
Cross-reference other models within the 18QHTF21 series from Mercury Electronics for alternative frequencies. Verify pinout compatibility before substituting with similar 4-SMD oscillators from other manufacturers. Ensure the replacement part supports the same 1.8V supply and LVCMOS output characteristics.
