The 8 MHz output combined with ±25 ppm stability keeps the clock edge within tight limits at 85°C — suitable for a UART baud-rate generator or USB full-speed clock. Supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails; the enable/disable function lets the system shut down the oscillator and pull the output to high-Z, dropping supply current from 35 mA max to 22 mA max — useful for sleep-mode power budgeting.
Design engineers need full electrical and timing specifications to validate fit into their circuit.
Buyers need immediate availability to avoid production delays.
Sourcing buyers compare costs across distributors to meet BOM budget.
Maintenance techs and brokers need drop-in replacements when the part is unavailable or obsolete.
Brokers and buyers need lifecycle status to decide on long-term availability and last-time buy.
Designers must ensure PCB layout compatibility before committing to the design.
