Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable within the specified operating range to ensure reliable oscillator performance. Ensure the PCB layout accommodates the 4-SMD no-lead package dimensions accurately to prevent soldering defects.
Selection Notes
Select this component when a precise 6.1784 MHz clock signal is required for systems operating on a 1.8V logic level. Consider the small form factor suitable for space-constrained designs. Evaluate the need for standby functionality if power efficiency during idle states is a critical design parameter for the target application.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co. Ltd, a supplier specializing in quartz crystals and oscillators. The series typically offers various frequencies within a standardized 2.0x1.6 mm SMD footprint. Mercury Electronics has a long history in the frequency control industry, providing components for diverse timing applications.
Replacement Considerations
Check for direct substitutes such as the 18QHTF21-8.0004-PD or 18QHTF21-18.1059-PD if different frequencies are acceptable. Ensure any replacement maintains the same 1.8V supply requirement and LVCMOS output type. Verify package compatibility for the 4-SMD no-lead configuration.
