Overview
The 18QHTF21-11.350-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 11.35 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component is designed for low-power applications and supports an operating temperature range typical for commercial grade devices.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Enable/Disable pin for active power management
- Compact 4-SMD no-lead surface mount package
Applications
- Low-power consumer electronics
- Digital signal processing systems
- Communication equipment requiring precise timing
Procurement Notes
Verify the specific suffix OE indicates the Enable/Disable functionality against the official datasheet. Confirm the 1.8V supply requirement matches the target circuit design. Ensure the 4-SMD no-lead package footprint aligns with the PCB layout specifications before ordering.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside precise frequency stability. The enable/disable feature makes it suitable for battery-operated devices where power conservation is critical. Compare package dimensions against available board space constraints.
Part Context
This model belongs to the 18QHTF21 series of XO oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The -OE suffix specifically denotes the presence of an enable control pin, distinguishing it from standard continuous-output variants like the -PD or non-controlled versions.
Replacement Considerations
Check for direct substitutes within the same series offering identical 11.35 MHz frequency and 1.8V supply. Verify that replacement parts also include the enable/disable control feature and match the 4-SMD no-lead package dimensions.
