This board connects to up to two EEM headers, but single-header operation is also possible, with limited number of 8 IOs.
Each RJ45 supplies 4 LVDS DIOs. The direction (input/output) is individually selectable for each signal via I2C or using on-board switches. Outputs are intended to drive 100 Ohm loads (LVDS is short-circuit protected), inputs are 100 Ohm terminated. The connectors dedicate all 8 pins to LVDS signals, ground is on the connector shield so only Ethernet cat 6 shielded cables are allowed. Maximum verified operating frequency is 150 MHz due to lab TTL generator limitation. IO buffers used in the design permit operation with much higher frequency.
