Crystals Procurement Notes

Verify the specific suffix 'IAR' against official CTS documentation to confirm packaging quantity and tape/reel specifications. Confirm that the ±10 ppm stability and 10 pF load capacitance match the circuit design requirements. Check for current availability status as distribution channels may list discontinued or backorder statuses. Ensure compliance with RoHS3 and REACH regulations for the target market.

Crystals Selection Notes

Select this component when a 38.4 MHz reference with tight ±10 ppm stability is required. The 10 pF load capacitance must align with the oscillator circuit's external capacitor values. The 60 Ohm ESR should be compatible with the driving strength of the host oscillator. Consider the -40°C to +85°C range if the application involves variable environmental conditions.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals, which are characterized by small footprints suitable for space-constrained designs. The 402 series typically offers fundamental mode operation with various frequency options and stability grades. The 'IAR' suffix likely denotes specific packaging or reel configuration details defined by the manufacturer.

Crystals Replacement Considerations

Direct substitutes must match the 38.4 MHz frequency, ±10 ppm stability, 10 pF load capacitance, and 60 Ohm ESR. Compatible packages include 4-SMD, No Lead with identical 2.00mm x 1.60mm dimensions. Verify temperature range compatibility (-40°C to +85°C). Cross-reference with other manufacturers' SMD crystals offering similar electrical parameters and mounting styles.
