The 6-pin VDFN footprint is common among MEMS oscillators — the same land pattern serves most Microchip DSC1xxx/DSC2xxx parts, so a single PCB layout can support multiple frequencies.","metaTitle":"DSC1222CI3-164M4257 – Microchip MEMS LVPECL Oscillator","metaDescription":"Active Microchip DSC1222 series XO, 164.4257 MHz LVPECL output, ±20 ppm stability, -40°C to 85°C, 6-VDFN package.
