Overview
The 18QHTF21-12.296-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 12.296 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and supports a Standby (Power Down) mode. It is housed in a 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.
Feature Summary
- Supports Standby (Power Down) functionality for power management
- Utilizes LVCMOS output logic for digital interface compatibility
- Compact 4-SMD No Lead surface mount package design
Applications
- Battery-powered portable devices
- General purpose clock signal generation
- Digital circuit timing references
Procurement Notes
Verify the specific operating temperature range and frequency stability specifications against the official datasheet before integration. Confirm that the 1.8V supply requirement aligns with the target system's power rails. Ensure the 4-SMD No Lead footprint matches the PCB layout constraints. Cross-reference the manufacturer part number to avoid confusion with similar variants in the series.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside a compact 2.0x1.6 mm footprint. The LVCMOS output is suitable for standard digital logic interfaces. Consider the Standby feature if power conservation during idle periods is a priority. Verify that the 12.296 MHz frequency meets the specific timing requirements of the application circuit.
Part Context
This model belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'PD' suffix indicates the inclusion of a Power Down or Standby control pin, distinguishing it from continuously running variants within the same physical package family.
Replacement Considerations
Direct substitutes include other 18QHTF21 series parts with identical 12.296 MHz frequency and 1.8V supply, such as those without the PD suffix if standby is not needed. Ensure any replacement maintains the 4-SMD No Lead form factor and LVCMOS output characteristics.
