With ±25ppm frequency stability and a wide supply range of 2.25V to 3.6V, this oscillator can serve as a single-device clock source for a PCIe reference, Ethernet PHY, or FPGA transceiver bank, reducing BOM clock-device count. The 14-VFQFN exposed-pad package (3.20mm x 2.50mm, 0.90mm height) requires a thermal via array under the pad for proper heat sinking and to keep the MEMS resonator within its stability band across the temperature range.","metaTitle":"DSC2044FI2-H0001 MEMS XO – Dual Output HCSL, 100-156.25 MHz","metaDescription":"Active Microchip MEMS XO, dual HCSL outputs, 100/106.25/125/156.25 MHz selectable.
