Crystals Procurement Notes

Verify the specific suffix 'D' against the manufacturer's current datasheet to confirm the exact load capacitance and ESR parameters, as these values can vary significantly between series variants. Ensure that the design schematic accounts for the 18pF load capacitance requirement to maintain the stated frequency accuracy. Confirm that the PCB footprint matches the 5.00mm x 3.20mm outline to prevent mechanical mounting issues during assembly.

Crystals Selection Notes

Select this component when a 15.36 MHz reference signal is required for digital logic or communication interfaces. The ±30 ppm tolerance is suitable for standard UART, SPI, or I2C bus timing where high precision is not critical. Consider the 60 Ohm ESR value when designing the oscillator circuit to ensure sufficient loop gain for reliable startup. The -20°C to +70°C temperature range defines the operational limits for industrial or commercial environments.

Crystals Part Context

This component belongs to the CTS 405 Series of surface mount crystals. The series offers various frequencies and package sizes optimized for space-constrained electronic designs. The 405C35D15M36000 specifically targets applications needing a 15.36 MHz clock source, which is a common baud rate multiplier in serial communication protocols.
