The 78Q2123 MicroPHY is designed to meet the growing demands of non-traditional networked applications such as set-top boxes, game consoles and digital TVs. The tiny size gives designers an edge when board space is at a premium and its single 3.3V supply requirements eliminates the need for 1.8V regulators. The integrated HP Auto-MDI/X function, a must for consumer electronic applications, automatically compensates for crossover cable problems eliminating one of the most common items for consumer help lines.Features
