Procurement Notes

Verify the specific suffix (OE) against official Mercury documentation to confirm exact electrical tolerances and pinout configurations. Ensure the operating temperature range meets the target application requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm that the 1.8V supply voltage aligns with the host circuit design before procurement.

Selection Notes

Select this oscillator when a precise 74.758333 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V supply constraint and 26mA current draw during power budgeting. The small 4-SMD footprint makes it suitable for space-constrained designs. Verify compatibility with the host processor's clock input specifications regarding rise and fall times.

Part Context

This component belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequencies with LVCMOS outputs and enable functions. The 18QHTF21 family is designed for modern digital applications requiring stable timing signals in compact form factors.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinouts and electrical characteristics but different frequencies. Verify that any replacement maintains the 1.8V supply requirement and LVCMOS output level. Check datasheets for equivalent performance in jitter and stability metrics.
