Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the datasheet for operating temperature ranges to guarantee reliability under your environmental conditions.

Oscillators Selection Notes

Choose this oscillator when a low-voltage 1.8V supply is required alongside LVCMOS outputs. The enable pin allows for dynamic power saving during idle states. Select this model if space constraints necessitate a small 4-pin SMD form factor. Consider the 35.252 MHz frequency specifically for communication protocols or data rates matching this value.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The '18' prefix typically indicates the 1.8V supply voltage requirement. The 'QHTF21' suffix denotes the specific package type and series characteristics within their product line. These components are designed for general-purpose timing applications in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 35.252 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent electrical parameters such as phase noise and jitter specifications. Check for compatible enable/disable logic levels. Ensure the replacement part meets the same operating temperature range and stability requirements.
