In computing, serialization (or serialisation) is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer) or transmitted (for example, across a network connection link) and reconstructed later (possibly in a different computer environment). ASNT1011-KMA is a low power and high-speed programmable multiplexer (MUX) 16-to-1 (16:1) or 8-to-1 (8:1). Out of the 19 pins, 8 are of particular interest as they form 4 TMDS differential pairs to transport the actual high-speed video info. The supported data representations. 60Gbps to 7.
