Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 14.336 MHz timing source is required for low-power applications. The choice depends on the necessity for an LVCMOS interface and the availability of a 1.8V power supply. Consider the physical size constraints of the 2.0x1.6mm package relative to other available oscillator options in the design.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystals and oscillators. The manufacturer has a history dating back to 1973, focusing on frequency control products.
