Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead package dimensions fit within the designated PCB footprint constraints to avoid mechanical interference during assembly.

Oscillators Selection Notes

Select this component when a precise 27.045 MHz clock source is required with low-voltage operation. Consider the enable/disable feature if dynamic power saving is necessary. Evaluate the LVCMOS compatibility with downstream digital inputs. Assess the thermal performance within the specified operating temperature range to ensure long-term reliability in the intended application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'OE' suffix typically denotes specific packaging or tape-and-reel configuration details as per manufacturer standards. This model provides a stable reference clock for digital systems requiring moderate precision.

Oscillators Replacement Considerations

Direct substitutes must match the 27.045 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical specifications such as phase noise and jitter if critical. Consult the manufacturer's cross-reference list for validated alternatives.
