Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific handling or reflow soldering profile recommendations provided in the official datasheet to ensure reliable assembly and long-term performance stability.

Oscillators Selection Notes

Select this component when a low-voltage, small-form-factor clock source is required. The LVCMOS output is suitable for standard digital logic families. Consider the standby feature if power efficiency is a priority. Verify that the 23.104 MHz frequency meets your system's timing needs. Ensure the operating temperature range specified in the datasheet covers your application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6mm package. These oscillators are designed for high-volume consumer and industrial electronics where size and power consumption are critical factors. The 'PD' suffix typically indicates the presence of a power-down control pin.

Oscillators Replacement Considerations

Direct replacements must match the 23.104 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify electrical parameters such as jitter and phase noise if strict timing accuracy is required. Cross-reference with other manufacturers offering similar small-footprint XO components.
