Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the 1.8V supply voltage aligns with the target system design. Confirm that the enable/disable pin configuration matches the control logic of the host circuit to ensure proper operational state management during integration.

Oscillators Selection Notes

Select this component when a precise 46.15787 MHz timing source is required within space-constrained designs. The choice is appropriate for systems operating at 1.8V that necessitate low-power standby modes via the enable feature. Consider the small footprint and leadless package type for high-density PCB layouts where traditional through-hole or larger SMD packages are unsuitable.

Oscillators Part Context

This part belongs to the QHTF series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific packaging or tape-and-reel configurations, though exact details require datasheet confirmation. This model represents a standard XO variant optimized for modern low-voltage digital applications.

Oscillators Replacement Considerations

Direct substitutes must match the 46.15787 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify electrical compatibility and pinout alignment. Consult manufacturer cross-reference lists for verified equivalents.
