Electrical characterization of a 500 MHz frequency EBGA package

We developed a 420-ball enhanced BGA (EBGA) package that can accommodate a 500 MHz ASIC with 15 W power consumption. This package uses a low voltage differential signal with 400 mV full amplitude and 240 ps risetime as its highest speed signal, and consists of 8 pairs of differential signals. Each pair is composed of 2 signals with an isometric length. Two… CONTINUE READING
