MEMS oscillator at 133.333 MHz — what it replaces
The supply voltage spans 1.8V to 3.3V, so it can run directly off a 1.8V core rail without an extra regulator. The MEMS base resonator means no quartz crystal start-up time and better resistance to vibration and shock — relevant for automotive cabin or outdoor telecom enclosures where mechanical stress is routine.
Package footprint and board layout fit
Housed in a 4-SMD, No Lead package measuring 5.00mm x 3.20mm with a seated height of 0.90mm. This is the industry-standard 5.0×3.2 mm oscillator footprint — it drops into the same PCB land pattern as most quartz XOs of this size, making it a direct drop-in replacement for a standard 133.333 MHz crystal oscillator in that package. The four pads are standard: supply voltage, ground, output, and a standby (power-down) control pin.
