Housed in a 6-VDFN package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm, it is a standard surface-mount footprint that fits most PCB layouts without a board spin. The supply voltage range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails, and the enable/disable function allows the output to be tri-stated for power savings or test mode.
Yes, it is a drop-in functional replacement for a 25.6 MHz quartz oscillator in the same 5.00 mm x 3.20 mm 6-VDFN footprint. The MEMS resonator offers tighter ±10ppm stability and better shock tolerance than a typical ±25 ppm quartz unit, but the pinout and supply voltage range (2.25 V to 3.6 V) are compatible with most standard XO designs. Verify the enable/disable logic polarity matches your circuit.
