18QHTF21-13.5212-OE

Overview

The 18QHTF21-13.5212-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.5212 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and features an Enable/Disable control interface for power management. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications.

Feature Summary

• LVCMOS output logic for digital signal compatibility
• Enable/Disable pin for active power control
• RoHS compliant construction
• Moisture sensitivity level 1 rating

Applications

• Timing and clock signal generation
• Embedded system clock sources
• Digital circuit synchronization

Procurement Notes

Verify the specific suffix OE indicates the Enable/Disable function rather than Standby mode found in other variants like PD. Confirm RoHS compliance status and MSL rating 1 availability through official Mercury documentation before finalizing procurement orders to ensure correct functional configuration.

Selection Notes

Select this component when a 1.8V supply and precise 13.5212 MHz timing are required. The Enable/Disable feature allows for dynamic power management compared to constant operation models. Ensure the 4-SMD no-lead package fits the target PCB footprint constraints.

Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronic Ind. Co., Ltd. The manufacturer specializes in quartz crystals and frequency control products. This specific model represents a standard XO variant within their portfolio of timing solutions.

Replacement Considerations

The 18QHTF21-13.5212-PD offers identical electrical specifications but uses a Standby (Power Down) control scheme instead of Enable/Disable. Verify that the control logic difference does not impact the system design before substituting.
