For a 90 MHz serial link, that tight stability keeps the bit-error rate within the receiver's jitter tolerance without external VCXO trimming.
Supply voltage range spans 1.8V to 3.3V, so the same BOM line can serve a 1.8V FPGA bank and a 3.3V MCU clock input without a separate level translator.
Housed in a 4-SMD, no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm. Surface-mount — the 4-pad land pattern matches standard 5×3.2 mm XO footprints, so a board already laid out for a quartz oscillator at this size accepts the MEMS part without a layout spin.
