# 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)
|
||
|
|
|
||
|
|
## Layout
|
||
|
|
- 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)
|
||
|
|
|
||
|
|
## Possible accessories using high-speed FFC connectors
|
||
|
|
- MIPI DSI smartphone-style LCDs
|
||
|
|
- MIPI CSI-2 cameras
|
||
|
|
- High speed ADC/DAC
|
||
|
|
- HDMI in/out, direct or using serialiser chip
|
||
|
|
- LVDS video in/out for LCDs or block cameras
|
||
|
|
- Breakout board to dual or triple PMOD
