Ffib Pwb - NEC NC1600C Service Manual

FFIB PWB (FPGA Formatter Interface Board)
In the Cinema circuit, the FFIB PWB enters the video data of the VIDEO processor and the SOFTWARE processor
in the LVTTL (3.3V) 16-bit EVEN/ODD format. After passing through various functional processing of Item 1
below, the data are transmitted to the FSB in the LVDS (2.5V) 16-pair format.
In the bootstrapping mode, configuration control is also carried out for each FSB.
