Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your power management architecture. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Validate the enable pin logic level compatibility with your controlling microcontroller or FPGA.

Selection Notes

Select this oscillator when a precise 104.116 MHz reference is needed in space-constrained designs. The LVCMOS interface ensures compatibility with standard digital logic families. The enable feature allows for power management during idle states. Consider the small 2.0x1.6 mm package size for high-density board layouts. Evaluate thermal performance if the device will operate near its maximum rated temperature limits.
