Overview
The 18QHTF21-80.700-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fundamental frequency of 80.700 MHz and utilizes an LVCMOS output interface. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- Provides stable clock generation with LVCMOS output compatibility
- Incorporates a standby mode to reduce power consumption during idle periods
- Utilizes a leadless SMD package for efficient surface-mount integration
Applications
- General electronic timing circuits
- Embedded system clock sources
- Data communication interfaces requiring precise frequency control
Procurement Notes
Verify the specific ordering suffix against official Mercury Electronics documentation to ensure the correct pinout and electrical characteristics. Confirm that the 1.8V supply requirement aligns with the target circuit design. Ensure the 4-SMD no-lead package dimensions match the PCB footprint specifications before finalizing procurement orders.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The 80.700 MHz frequency must be validated against the system's clock input requirements. Consider the standby feature if power efficiency is a critical design constraint for the application environment.
Part Context
Mercury Electronics Ind. Co., Ltd. is a recognized manufacturer of frequency control products, including quartz crystals and oscillators. The company has a history of producing components for automotive and industrial sectors. This model belongs to their series of standard XO devices designed for reliable timing performance.
Replacement Considerations
Consult official Mercury Electronics cross-reference lists for verified substitutes. Ensure any replacement maintains the 80.700 MHz frequency, 1.8V operating voltage, and LVCMOS output type. Verify package compatibility for the 4-SMD no-lead form factor.
