Procurement Notes

Verify the specific suffix 'B' against official QST documentation to confirm exact electrical characteristics and pinout configuration. Ensure the ordering part number matches the required frequency tolerance and package variant. Confirm RoHS compliance status with the manufacturer or authorized distributor prior to purchase. Validate that the supply voltage requirements align with the target circuit design specifications.

Selection Notes

Select this component when a 49.152 MHz CMOS clock source is required for embedded systems. Consider the ±50ppm stability requirement for timing-sensitive applications. Evaluate the 3.3V supply constraint against available power rails. Compare physical footprint constraints with the 7.0x5.0mm package dimensions against board layout limitations.
