Omitting C52 reduces ripple in the +3V3 supply.
Remove C40 and C47. Move C6 closer to U3.
remove FORCE_RECOVERY button
renumber button references
remove FPGA connections to U6 and replace with test points:
CS_DI
FPGA_CONFIG_CLK
FPGA_DONE
FPGA_INIT
DEBUG_SPI_MISO
DEBUG_SPI_MOSI
DEBUG_SPI_CLK
DEBUG_SPI_CS
Footprint is designed for Kycon KUSBXHT-SB-AS1N-B30-NF in order to fit a wide variety of compatible parts.
update load switch input and output capacitors add GND zone on In2.Cu under J3 data signals
Thanks for the footprint, Glasgow!
eliminate +1V8 supply
add more user i/o signals route LVDS pair to SMA connectors (J8, J9)
3.2x2.5 mm package has lower price and wider availability of substitutions
Enclosures and test jigs may now be designed that fit the PCB in only one orientation.
specify CC resistors as ±10% to hint that the spec requires it add resistance value to resistor networks give UART nets top-level names indicating JTAG functions change AP22811 values to AP22811A change PMOD to Pmod nudge FPGA_TMS trace to make it more bodgeable
