Main Device
Block, IC Function
Regulator block Ge3.3V and +2.5V power from +5V power supplied by AVIB
Clock control block
Generate 27MHz and 36.864MHz clocks for video and audio from 27MHz clock supplied by AVIB, and
supply to each IC
Clock generation block
Generate 18.432MHz that are a basic clock for RS-232C I/F of FPGA
Work with asynchronization for a audio 36.864MHz clock of the clock control block
Generate 27MHz to use for the simple signal generator function for board check
FPGA (IC8611)
FPGA Communication with RS-232C for inside status display
Communication control with AVIB
Operation setting of each IC in the board and the LED control for status display
CCIR656 video data control
3-wires audio data control
Sampling frequency 96kHz of audio data convert to 48kHz
Generate 6.144MHz and 12.288MHz clocks for audio (dividing by 36.864MHz clock)
Simple signal generator function for board check (switching by a DIP switch)
Digital audio transmitter
(IC8614)
Convert 3-wires audio data from the FPGA into AES/EBU data
Embedded audio processor
(IC8613) Superimposing the 3-wires audio data from the FPGA on the CCIR656 video data from the FPGA, and
convert 8-bit to 10-bit.
Digital video serializer
(IC8617)
Convert 10-bit CCIR656 video data from the embedded audio processor to SDI serial data
