Ultimate ECP5 Board

Key Features

Largest ECP5; LFE5UM5G-85F
PCIe 2.0 x2 card edge connector on two SERDES channels
Remaining two SERDES channels muxed using high-speed mux:
- 2-lane mini DisplayPort transmit and receive connectors
- or USB type-C connector (with proper CC logic and ULPI PHY for USB 2.0)
- Must have flexible SERDES clocking for a range of protocols with passive adapters (SFP, SATA, etc)
1GByte or 2GByte x32 DDR3, either chips or half SODIMM
Dedicated HDMI output, probably using TFP410 serialiser for a simpler video output than DP
Dual GbE connectors with RGMII PHYs
USB-A 2.0 host connector with ULPI PHY
2nd USB-A connector directly connected to FPGA
FT2232H for debug JTAG and UART/FIFO on second USB type-C connector also used for normal board power (up to 5V 3A)
Optional PCIe 12V power input connector
At least 8 user LEDs, 4 user buttons, 4 or 8 user DIP switches
128Mbit QSPI flash for boot and data
microSD card connector
Audio I/O with I2S codec
Dual PMOD connector
As many remaining IO as possible on high speed FFC connectors with a differential optimised pinout (at least 100-150 IO using this)

PCIe card form factor
At least Ethernet, 2x miniDP and 2x USB-C on exposed side when in a case used as a PCIe card
Other connectors probably would have to be on other sides. FFC connectors probably on top so they can loop over to another card to form a 2-slot card (e.g. with ADCs/DACs for SDR/DAQ)
