The DS1090U-32+ tops out at 250 kHz. That is a low-speed clock — think microcontroller watchdog timers, spread-spectrum clocking for EMI reduction, or a simple system clock for a slow peripheral bus. It will not drive a high-speed serial interface or a processor core clock. If the BOM needs a faster reference, this is not the part.
Housed in an 8-uMAX/uSOP surface-mount package (3.00 mm body width, 0.118" pitch), the part occupies minimal board area. The supplier device package is 8-uMAX/uSOP.
The maximum output frequency is 250 kHz. There is no minimum frequency specified in the listing; the part can generate clocks down to DC (0 Hz) since it is a divider-based generator.
Yes, it is ROHS3 compliant, meeting the latest EU restriction directive.
