Procurement Notes
Verify the specific suffix 'OE' indicates the enable/disable feature as documented. Confirm the operating temperature range and load capacitance requirements against the target system design. Ensure the 1.8V supply rail stability meets the oscillator's specifications to maintain frequency accuracy. Cross-reference the pinout diagram with the PCB layout to prevent installation errors.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside precise 64.152 MHz timing. The small 2.0x1.6mm footprint makes it ideal for dense circuit boards. Consider the enable pin requirement if dynamic power saving is necessary. Compare against other Mercury series oscillators for alternative frequencies or package sizes if this specific configuration does not fit the mechanical constraints.
Part Context
This part belongs to the Mercury Electronics SMD oscillator family, which specializes in quartz-based frequency control products. The company has been manufacturing these components since 1973, focusing on reliability and precision. This specific model utilizes standard XO technology within a miniature package format common in modern portable devices.
Replacement Considerations
Direct substitutes include other 64.152 MHz LVCMOS oscillators with 1.8V supply and similar 4-SMD packages. Verify that any replacement supports the same enable/disable logic level and physical dimensions. Check for equivalent frequency stability and phase noise specifications to ensure system performance is maintained.
