This frequency and output type are a direct fit for 10GbE, Fibre Channel, and SONET/SDH reference clocks where the differential LVPECL swing provides the noise margin needed over long board traces. The wide supply voltage range of 2.25V to 3.6V means it can run from a 2.5V or 3.3V rail without a dedicated regulator, simplifying the power tree on dense mixed-voltage boards. Housed in a 7.00mm x 5.00mm 6-SMD package with no-lead exposed pad, the footprint matches standard 7x5 mm oscillator land patterns.","metaTitle":"DSC1122AI2-155.5200 Microchip MEMS XO 155.52 MHz LVPECL","metaDescription":"Microchip DSC1122AI2-155.5200 MEMS XO, 155.52 MHz LVPECL output, ±25 ppm stability, 2.25-3.6V supply, -40°C to 85°C.
