Supply voltage spans 2.25V to 3.6V, so it runs on a 2.5V or 3.3V rail without a separate regulator — the LVPECL output swing scales with the supply, so the termination network must be calculated for the actual VCC used. ## Package and rework — 6-SMD no-lead Housed in a 6-SMD no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm — a compact footprint that reflows easily with standard solder profiles.","metaTitle":"DSC1122CE5-047.9980T MEMS XO, 47.998 MHz, LVPECL, Active","metaDescription":"Microchip DSC1122CE5-047.9980T: XO (Standard) MEMS oscillator, 47.998 MHz, LVPECL output, ±10ppm stability, 6-SMD package.
