What this MEMS XO does on your board
The output frequencies are factory-programmed to 10 MHz, 27 MHz, 148.5 MHz, and 125 MHz, covering common video pixel clocks (148.5 MHz for 1080p), Ethernet reference (125 MHz for 1GbE), and logic/audio domains.
The wide supply range of 2.25V to 3.6V means it runs directly from a 3.3V or 2.5V rail without an extra LDO — the internal regulator handles the MEMS core voltage.
Housed in a 20-VFQFN with exposed pad, the 5.00 mm × 3.20 mm footprint is compact enough for space-constrained designs, but the exposed pad requires a thermal via pattern under the package for proper solder-joint reliability and heat sinking. The 0.90 mm height keeps it low-profile for mezzanine card stacking.
