2.488 MHz MEMS oscillator — what drives the BOM fit
Supply voltage spans 2.25V to 3.6V, so it runs from a single 2.5V or 3.3V rail without an external LDO — one less part on the BOM.
Temperature grade and frequency stability
Absolute Pull Range (APR) is ±10 ppm, which means the output frequency stays within 10 ppm of 2.488 MHz over the full temperature and voltage range — tight enough for most UART, SPI, and I2C clocking without a separate VCXO.
Package and PCB layout notes
Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a low-profile, small-footprint clock source that fits under a shielding can or on a dense mixed-signal board.
