Because the dual-frequency output (74.1758/74.25 MHz) is tightly coupled to video standards, a replacement would need to match both frequencies in a single package — a parametric search on MEMS XOs with those exact outputs and a 4-VDFN footprint is the practical cross-reference path.","metaTitle":"Microchip DSC6121CI2A-00AJ XO, MEMS, 74.1758/74.25MHz","metaDescription":"Microchip DSC6121CI2A-00AJ MEMS XO, 74.1758/74.25MHz CMOS, ±25ppm, 1.71-3.63V, -40~85°C, 4-VDFN.
