Oscillators Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct packaging configuration. Confirm that the required operating temperature range aligns with system environmental constraints. Cross-reference the pinout diagram with PCB layout specifications to guarantee proper electrical connectivity and mechanical fit within the target design.

Oscillators Selection Notes

Select this model when a 55.32 MHz frequency is strictly required for the application timing. Ensure the circuit design supports the 1.8V supply rail and accommodates the LVCMOS signal levels. Consider the physical footprint constraints of the 5.0x3.2 mm package during the mechanical design phase to ensure adequate clearance on the printed circuit board.

Oscillators Part Context

This component belongs to the H53 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized small outline package. The designation indicates a quartz-based oscillator optimized for cost-effective mass production while maintaining stable frequency performance for standard digital applications.

Oscillators Replacement Considerations

Direct substitutes must match the 55.32 MHz frequency, 1.8V supply, and LVCMOS output type. Verify that any alternative part fits the 4-SMD no-lead form factor. Check datasheets for equivalent load capacitance and drive strength requirements to ensure seamless integration without circuit modification.
