It outputs a CMOS-level clock signal from a 2.25 V to 3.63 V supply rail, drawing 27 mA typical at full load.
Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, this oscillator fits tight-profile automotive PCBs. The surface-mount footprint is straightforward — no special via-in-pad or thermal relief needed.
Yes. The supply voltage range is 2.25 V to 3.63 V, so a 3.3 V rail is within spec. The CMOS output swings rail-to-rail at that voltage.
Within the DSC12X1 series, other frequency variants share the same 6-VDFN package and pinout. For a direct 25 MHz replacement, any DSC12X1 part with the same package and supply range is a functional match — confirm the Enable/Disable polarity and frequency stability (±25 ppm) before substituting.
