MEMS resonator, four clock outputs, one package
It delivers three fixed LVCMOS outputs at 25 MHz, 24 MHz, and 33.333333 MHz, plus a fourth output that can be configured via the enable/disable function — the 24 MHz rail is often the USB or Ethernet reference, while 33.333333 MHz feeds a PCIe or SATA PHY. The ±50 ppm frequency stability across the full -40°C to 85°C industrial range keeps the clock edge jitter within the timing budget for most 100BASE-TX and USB 2.0 PHYs without needing an external PLL cleanup.
Supply flexibility and enable/disable control
The 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails directly — no intermediate LDO required, which saves a component and a decoupling cap on the BOM.
The 20-VFQFN package with exposed pad (5.00mm x 3.20mm, 0.90mm height) requires a thermal via pattern under the pad for proper heat sinking — the datasheet layout recommendation should be followed to keep the MEMS die within its operating temperature range.
