Overview
The 18QHTF21-13.288-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.288 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.
Feature Summary
- Supports low-voltage operation at 1.8V
- Includes standby power-down capability
- Utilizes LVCMOS output interface
Applications
- General electronic circuits requiring precise timing
- Embedded systems utilizing LVCMOS interfaces
- Portable devices due to low voltage requirements
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's specifications. Confirm that the 4-SMD no-lead package footprint aligns with your PCB layout constraints. Cross-reference the manufacturer datasheet for thermal and electrical limits.
Selection Notes
Select this component when a 13.288 MHz clock signal is required with LVCMOS compatibility. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. The integrated standby feature allows for power management in battery-operated applications. Consider the small 2.0x1.6mm form factor for space-constrained designs.
Part Context
This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within the same physical footprint. The 'PD' suffix indicates the inclusion of a power-down pin or function. These components are designed for high reliability in consumer and industrial electronics.
Replacement Considerations
Direct substitutes must match the 13.288 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify if alternative manufacturers offer identical pin-out configurations and electrical characteristics. Ensure any replacement supports the standby functionality if required by the system design.
