Supply voltage spans 2.25 V to 3.6 V, so the same oscillator works on a 2.5 V FPGA bank or a legacy 3.3 V ASIC rail. The 58 mA max supply current at 150.5 MHz is typical for an LVPECL output stage driving a 50-Ω terminated line. Housed in a 6-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The DSC1122 series is in volume production, so the BOM line carries no last-time-buy risk.","metaTitle":"DSC1122CI2-150.5000 MEMS Oscillator – LVPECL 150.5 MHz","metaDescription":"Microchip DSC1122CI2-150.5000 XO (Standard) with LVPECL output, 150.5 MHz, ±25 ppm stability, -40°C to +85°C.
