• Utilizes a low-profile 4-SMD no-lead surface mount package

Oscillators Applications

• Timing and clock signal generation in electronic devices
• Embedded systems requiring precise frequency references
• Portable electronics utilizing low-voltage power supplies

Oscillators Procurement Notes

Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm the enable/disable functionality and exact electrical parameters. Ensure the 1.8V supply requirement aligns with the target system design. Confirm the 4-SMD package footprint matches the PCB layout specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 35.478 MHz reference is required with low-voltage operation. The enable/disable feature makes it suitable for battery-powered applications where power conservation is critical. Ensure the LVCMOS output level is compatible with the receiving logic inputs of the host circuit.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor oscillators. The series typically offers various frequencies within a 2.0x1.6mm package. The OE suffix indicates specific operational characteristics compared to other variants like PD or standard outputs.

Oscillators Replacement Considerations

Direct substitutes must match the 35.478 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm footprint. Verify that any replacement part also supports the enable/disable control function if required by the design.
