Overview
The 18QHTF21-66.67333-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 66.67333 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications with a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated enable and disable control functionality
- Compact 4-SMD no lead surface mount package
Applications
- General clock signal generation in electronic circuits
- Digital system timing references
- Embedded device clock sources
Procurement Notes
Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure correct pinout and electrical specifications. Confirm that the 1.8V supply voltage requirement aligns with the target circuit design. Check for any recent revisions to the 4-SMD package dimensions to ensure mechanical fit within the assembly constraints.
Selection Notes
Select this component when a precise 66.67333 MHz clock source is required for LVCMOS-compatible digital logic. The choice is driven by the need for a low-profile 2.0x1.6mm footprint and the integration of enable/disable controls. Ensure the application environment supports the specified operating temperature range and voltage levels defined in the official documentation.
Part Context
This part belongs to the 18QHTF series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and package options. The '18' prefix typically indicates the 1.8V supply voltage capability, while 'QHTF' denotes the specific product line characteristics. This model represents a fixed-frequency solution within the broader portfolio of frequency control products.
Replacement Considerations
Direct substitutes must match the 66.67333 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD 2.0x1.6mm package. Verify pin-to-pin compatibility and electrical parameters before substitution. Consult the manufacturer's cross-reference list for approved alternatives.
