3QHTF21-22.080-PD

Oscillators Overview

The 3QHTF21-22.080-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 22.08 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 3.3V and features a standby or power-down mode capability. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component is suitable for applications requiring precise clock signals in space-constrained electronic designs.

Oscillators Feature Summary

• Supports low-voltage CMOS output logic for digital interface compatibility
• Includes standby functionality to reduce power consumption during idle periods
• Utilizes surface-mount packaging for automated assembly integration

Oscillators Applications

• General-purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring stable frequency sources

Oscillators Procurement Notes

Verify the specific manufacturer part number against official Mercury Electronics documentation to ensure authenticity. Confirm that the required operating temperature range and load capacitance specifications align with the target circuit design. Check for any specific ordering suffixes that may indicate variations in tape-and-reel packaging or lead-free compliance status before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 22.08 MHz clock source is required in a 2.0x1.6mm footprint. Ensure the system voltage matches the 3.3V requirement. Consider the LVCMOS output swing limits relative to downstream logic inputs. Evaluate the need for standby control if power management is a critical design constraint for the application environment.

Oscillators Part Context

This oscillator belongs to the 3QHTF21 series from Mercury Electronic Ind. Co., Ltd, which specializes in frequency control products including quartz crystals and oscillators. The company has a long history in Taiwan's quartz industry. This specific model represents a standard XO variant within their portfolio, distinct from TCXO or VCXO types, offering fixed frequency performance without external tuning voltages.

Oscillators Replacement Considerations

Direct substitutes must match the 22.08 MHz frequency, 3.3V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as current consumption and startup time. Cross-reference with other manufacturers' equivalent series ensuring identical mechanical and electrical specifications for drop-in replacement.
