Overview
The 18QHTF21-86.996875-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 86.996875 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an Enable/Disable control feature 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
- Supports LVCMOS output logic for digital interface compatibility
- Features Enable/Disable functionality for active power control
- Utilizes a low-profile 4-SMD No Lead surface-mount package
Applications
- Digital signal processing systems requiring precise clocking
- Communication equipment utilizing LVCMOS interfaces
- Embedded systems with 1.8V power domains
Procurement Notes
Verify the specific suffix 'OE' corresponds to the Enable/Disable function rather than Standby mode, as other variants like '-PD' exist within the same series. Confirm the operating temperature range and load capacitance requirements against the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when a stable 86.996875 MHz reference is required for LVCMOS-based circuits. Ensure the board layout supports the 4-SMD No Lead footprint dimensions. Consider the 1.8V supply constraint and verify that the Enable pin logic levels align with the controlling microcontroller or FPGA outputs.
Part Context
Mercury Electronic Ind. Co., Ltd. is a manufacturer specializing in frequency control products, including quartz crystals and oscillators. This part belongs to their XO series, which provides standard clock signals for electronic applications. The company has a history of producing various timing components for industrial and commercial use.
Replacement Considerations
The 18QHTF21-31.996875-PD is a related variant from the same manufacturer but differs in frequency, output logic type, and standby functionality. Direct substitution requires verifying electrical compatibility and pinout alignment.
