Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required enable/disable configurations and output load specifications. Confirm that the 3.3V supply requirement aligns with the target system's voltage rails. Ensure the 4-SMD no-lead footprint matches the PCB land pattern design to prevent soldering defects during assembly.

Oscillators Selection Notes

Select this component when a precise 15.437823 MHz reference is required for low-power applications. The enable feature allows for dynamic power reduction in battery-operated devices. Consider the small 2.0x1.6mm footprint for space-constrained designs requiring standard LVCMOS signaling without additional buffering components.

Oscillators Part Context

This part belongs to the 3QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequency options within a standardized small outline package. These oscillators are designed for high reliability in consumer and industrial electronics, providing stable frequency generation with minimal electromagnetic interference compared to older through-hole technologies.

Oscillators Replacement Considerations

Direct substitutes include the 3QHTF21-15.437823-PD variant from Mercury United Electronics, Inc., which shares identical electrical characteristics and pinout configuration. Verify that any replacement maintains the same LVCMOS output type and 3.3V operating voltage to ensure functional equivalence in the existing circuit design.
