A single device can clock a PCIe reference (100 MHz), a 1 GbE PHY (125 MHz), and a processor core (150 MHz) without external fanout buffers or multiple oscillators. ## ±25 ppm stability and supply range Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails commonly found on networking and compute boards. ## Active production and package footprint The 20-VFQFN with exposed pad (5.00 mm × 3.20 mm body, 0.90 mm height) requires a thermal via array under the pad for proper heat transfer to the PCB ground plane.","metaTitle":"DSC400-4444Q0015KE2T MEMS XO – 6-Output HCSL Clock Generator","metaDescription":"Microchip DSC400-4444Q0015KE2T: Active MEMS XO, 6 outputs (25/50/125/150/100/156.25 MHz), HCSL, ±25 ppm, Enable/Disable, 20-VFQFN.
