HCSL (High-Speed Current Steering Logic) swings 700-900 mV peak-to-peak into a 50-Ω termination to Vcc-2V, which means the output amplitude is set by the termination, not the supply — the same board layout works across the full 2.25V to 3.6V supply range. ## ±25 ppm stability over industrial temperature The 6-VDFN package (3.20mm x 2.50mm, 0.90mm seated height) is a standard MEMS oscillator footprint, compatible with common quartz XO layouts — verify the pad pitch against your existing land pattern before committing.","metaTitle":"DSC1124CI2-133.3300 – Microchip MEMS XO, 133.33 MHz, HCSL","metaDescription":"Active MEMS XO from Microchip, 133.33 MHz HCSL output, ±25 ppm stability, -40°C to 85°C, 6-VDFN.
