Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Check the operating temperature range specifications to ensure reliability under your intended environmental conditions. Validate the package footprint compatibility with your PCB layout.

Oscillators Selection Notes

Select this oscillator when a stable 27.07 MHz reference is required for LVCMOS-compatible devices. Consider the 1.8V supply constraint and the availability of a standby control line for power management. Evaluate the size constraints of the 2.0x1.6mm package against available board space. Compare jitter specifications if high-frequency stability is critical for your application performance.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized surface-mount format. The series is characterized by its low profile and compatibility with automated assembly processes. Mercury Electronics has established itself as a manufacturer of frequency control products since 1973, providing quartz-based solutions for global markets.

Oscillators Replacement Considerations

Direct replacements must match the 27.07 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package dimensions. Verify that substitute components offer equivalent electrical characteristics and thermal performance. Cross-reference pinouts and standby functionality to ensure seamless integration without circuit modification.
