Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific RoHS or environmental compliance documentation if required for your region.

Oscillators Selection Notes

Select this component when a precise 26.985 MHz clock source is required with low voltage operation. The LVCMOS output is suitable for standard digital logic families. Consider the small 2.0x1.6 mm package size for space-constrained designs. The power-down feature offers energy efficiency benefits for battery-operated applications.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically includes various frequencies such as 8.0 MHz, 18.1059 MHz, 50.2067 MHz, 51.2 MHz, 96.768 MHz, and 26.9865 MHz.
