Figure 2-10-1：Power Supply on core board schematic
The core board is powered by +5V, converted to +1.0V by a 1 channel
DC/DC power chip TPS54620, and the output current can be as high as 6A. It
is converted into +1.8V and +1.5V power supply through 2 DC/DC power chip
TLV62130RGT, and the output current can be up to 3A per channel. In addition,
VCCIO power supply and +3.3V power supply are generated by 2-way LDO
SPX3819M5-3-3. VCCIO mainly supplies power to BANK15 and BANK16 of
FPGA. Users can adapt other voltages of BANK15,16 to different voltages by
replacing other LDO chips. The standard allows differential signals connected
to BANK15 and BANK16 to implement LVDS data communication at different
level standards. The functions of each power distribution are shown in the
following table:
