Procurement Notes
Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm exact electrical characteristics and pinout configuration. Ensure the required operating temperature range aligns with the datasheet specifications for the intended environment. Cross-reference the package outline drawing to confirm mechanical fit within the target assembly constraints before finalizing procurement orders.
Selection Notes
Select this component when a 1.8V supply voltage is available and LVCMOS outputs are required. Consider the 2.0x1.6mm footprint for PCB layout constraints. Evaluate if the standard oscillator performance meets the jitter and stability requirements of the application compared to lower phase noise alternatives.
Part Context
This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronic Ind. Co., Ltd. The series offers various frequencies and supply voltages. The 115.12 MHz variant provides a specific clock rate for high-speed digital interfaces. The manufacturer specializes in quartz frequency control products.
Replacement Considerations
Check for parts with identical 115.12 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package dimensions. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
