That pair of frequencies is a common combination for 10 Gigabit Ethernet and Fibre Channel reference clocks — the 153.6 MHz drives the SerDes PLL and the 155.46875 MHz feeds the line-side PHY, all from a single 5.00 mm x 3.20 mm package. ## Supply flexibility and enable/disable control The 2.25 V to 3.6 V supply range means this oscillator can run directly from a 2.5 V or 3.3 V rail without an intermediate LDO — the internal regulator handles the headroom. ## Industrial temperature grade and active lifecycle ## 20-VFQFN exposed pad — layout consideration The 0.90 mm height keeps it compatible with standard mezzanine card clearances.","metaTitle":"DSC400-0202Q0106KI1 XO 153.6MHz/155.46875MHz LVPECL MEMS","metaDescription":"DSC400-0202Q0106KI1 dual-output LVPECL XO from Microchip: 153.6MHz & 155.46875MHz, ±50ppm stability, 2.25V–3.6V supply, -40°C~85°C.
