Overview
The 18QHTF21-59.300-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 59.3 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, supporting 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. This surface-mount oscillator is suitable for digital circuits requiring precise clock signals.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated enable/disable control functionality
- Compact 4-SMD no-lead surface mount package
Applications
- Digital signal processing systems
- Communication equipment clocking
- Embedded microcontroller systems
Procurement Notes
Verify the specific suffix 'OE' against the manufacturer's official datasheet to confirm the exact enable/disable configuration and voltage level. Ensure the 4-SMD footprint matches the PCB design requirements. Cross-reference the 59.3 MHz frequency specification with system timing constraints before procurement.
Selection Notes
Select this component when a 1.8V supply voltage is required alongside LVCMOS outputs. The enable/disable feature makes it suitable for power-sensitive designs. Verify that the 2.0x1.6mm package size fits within the available board space constraints compared to larger oscillator packages.
Part Context
This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'OE' suffix likely denotes specific operational characteristics such as the enable pin configuration, distinguishing it from other variants in the same physical package family.
Replacement Considerations
Direct substitutes include other 18QHTF21 series parts with matching 59.3 MHz frequency and 1.8V operation. Verify pinout compatibility and electrical specifications before replacing with generic industry equivalents.
