Supply voltage spans 2.5V to 3.3V, so the same BOM line works on a 2.5V FPGA bank or a 3.3V ASIC rail without a separate LDO. The 4-VDFN exposed pad package measures 7.00mm x 5.00mm with a seated height of 0.90mm — a standard footprint that matches many 7x5 mm SMD oscillators.
Active draw is 7.5mA max at full output load — a 4000x reduction between run and sleep, which matters for battery-powered edge devices that wake briefly to transmit and then sleep.

Yes, electrically it is a drop-in replacement for a 156.25 MHz LVCMOS quartz oscillator in the same 7x5 mm SMD footprint. The MEMS resonator provides better vibration tolerance and typically lower phase noise than a quartz crystal, but the output logic and timing are identical — no board spin required.
Yes, the part includes a standby (power down) function. When the enable pin is pulled low, the output is disabled and the supply current drops to 1.8µA typ.
