Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 3.3V supply voltage aligns with the target circuit design. Ensure the 4-SMD package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a stable 49.5 MHz reference is required with low-power standby capabilities via the enable pin. Consider the LVCMOS output swing levels to ensure compatibility with downstream logic inputs. Evaluate the thermal performance and operating temperature range to confirm suitability for the intended environmental conditions within the final electronic assembly.

Oscillators Part Context

This part belongs to the 3QHTF57 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and enable features. The -OE suffix typically denotes specific packaging or tape-and-reel configurations as defined by the manufacturer's ordering guidelines for this specific product line.

Oscillators Replacement Considerations

Direct substitutes must match the 49.5 MHz frequency, LVCMOS output type, 3.3V supply, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical. Consult the manufacturer's cross-reference list for validated equivalent parts ensuring identical functional parameters.
