Recently need to design the av products have HDMI and Ethernet communication, check the cable will, on the wiring of great advantage, but the chip is very expensive, the design is very complex,

Don't understand, why do so many pins?? GBA encapsulation of hundreds of pin cable will chip?

19 root HDMI + 20 GMII, eight RJ45, use a QFP64 feet with respect to OK, why hundreds of pins of BGA?

It is better to directly use HDMI + gigabit RJ45, design is simple, cheap, moreover, the HDMI pass more than 10 meters, most of the occasion will be enough,

With cable will only suitable for long distance transmission, the application market is very small,

Experienced friend please answer, thank!

BGA is a matrix of hundreds of pin, single way to send and receive a QFN96, excluding Ethernet,
