Programmable Timers And Oscillators Procurement Notes

Verify the specific ordering suffix 'XL' against the manufacturer's latest product standards to confirm tape-and-reel packaging specifications. Ensure the selected frequency matches the design requirements, as the datasheet lists 10 MHz to 40 MHz as the supported range. Cross-reference thermal dissipation limits if operating near the upper ambient temperature boundary.

Programmable Timers And Oscillators Selection Notes

Select this component for applications requiring minimal external parts and low standby current. The integrated regulator simplifies power management compared to discrete oscillators. Verify that the target frequency falls within the 10 MHz to 40 MHz operational window. Consider the 833.3 °C/W thermal resistance when designing PCBs for high ambient temperatures without heat sinks.

Programmable Timers And Oscillators Part Context

This part belongs to Panasonic's line of low-power crystal oscillator ICs. It serves as a direct replacement for older discrete oscillator solutions in portable electronics. The SSMTXL designation indicates a specific surface-mount variant optimized for automated assembly processes in consumer hardware manufacturing.

Programmable Timers And Oscillators Replacement Considerations

Check pinout compatibility with existing PCB footprints. Verify that the new oscillator's frequency tolerance and stability meet the system clock requirements. Confirm that the 2.3 V minimum start-up voltage is sufficient for the target application's power rail conditions.
