For applications requiring better than ±20 ppm, consider the ±10 ppm variant in the same DSC61XXB family. ## Package, footprint, and assembly considerations The four terminals are on the bottom — no side leads — so the PCB footprint is a simple 2x2 array of pads. Standard reflow soldering applies; the MSL (Moisture Sensitivity Level) is typically Level 1 for MEMS oscillators from Microchip, meaning no bake required before assembly. Supplied in Tape & Reel packaging, it is ready for automated pick-and-place. The reel quantity (typically 3000 pcs per reel) affects procurement MOQ — confirm the reel count with your distributor when quoting.","metaTitle":"Microchip DSC6121JI3B-01VKT MEMS XO, 12.7281/13.2256MHz","metaDescription":"Microchip DSC6121JI3B-01VKT MEMS oscillator, XO type, dual output 12.7281MHz & 13.2256MHz, CMOS, ±20ppm, 1.8-3.3V, -40~85°C, 4-VLGA.
