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. Always refer to the official datasheet for final electrical characteristics.

Oscillators Selection Notes

Select this component when a low-profile, low-voltage oscillator is required for timing applications. The 2.0x1.6mm footprint is suitable for dense PCB layouts. Consider the standby feature if power efficiency is a critical design constraint. Ensure the 29.44 MHz frequency matches the system clock requirements. Verify that the LVCMOS output swing meets the input thresholds of downstream components.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co. Ltd, which offers various frequencies in a small form factor. The series is characterized by its leadless SMD construction and support for low voltage operation.
