Programmable Timers And Oscillators Procurement Notes

Verify the specific package variant required; the standard part number denotes an 8-pin SOIC in tube packaging. The 'WE' suffix indicates Pb-free and Green compliance. For tape and reel packaging, the ordering code requires an 'X' suffix. Confirm that the application design accommodates the necessary external components, specifically the quartz crystal and bypass capacitors.

Programmable Timers And Oscillators Selection Notes

Select this component when a tunable clock source is needed within the 19.44 MHz to 40 MHz range. Ensure the external crystal meets the specified load capacitance of 18pF and ESR of 35Ω max. The device requires a 3.3V supply and operates within an ambient temperature range of -40°C to +85°C. Verify that the required pull linearity and jitter specifications align with system requirements.
