Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications 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 to guarantee reliable signal integrity and proper operation within the intended application environment.

Oscillators Selection Notes

Select this component when a precise 29.9089 MHz clock source is required for low-power applications. The choice is driven by the need for a small form factor due to the 2.0x1.6mm package size. Consider the 1.8V supply requirement and LVCMOS compatibility with downstream logic. The inclusion of a power-down feature may be critical for systems requiring energy management capabilities during idle states.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in frequency control products.
