For simple TTL signals, we offer I/O cards in the EEM form factor with 8 channels over BNC (2118), SMA (2128) or MCX (2138) connectors. The IOs are divided into two banks of 4, with per-bank ground isolation. The direction (input/output) and termination (high-Z/50R) is selectable on a per-channel basis via I2C or on-board switches. The open circuit voltage of outputs is 5V, and outputs can supply a valid TTL level into 50Ω and tolerate an indefinite short circuit to ground.

When higher densities or faster speeds are required, the Sinara 2238 MCX card is available. It provides 16 non-isolated channels in 4hp of space using MCX connectors. The card is bidirectional, with the direction controlled in groups of 4 channels. Each IO can be individually terminated with 50Ω.
For even higher-density or even faster signals, the Sinara 2245 is an extension module supplying 16 LVDS pairs via 4 front-panel RJ45 connectors.
Each RJ45 supplies 4 LVDS DIOs. The direction (input/output) is individually selectable for each signal via on-board switches. Outputs are intended to drive 100Ω loads (LVDS is short-circuit protected), inputs are 100Ω terminated. The connectors dedicate all 8 pins to LVDS signals, ground is on the connector shield so only shielded Ethernet cat 6 shielded cables are allowed.
All outputs can be configured either as 3.3 or 5V. They can drive 50R load when set to 5V. FPGA can is configured from on-board FLASH. FLASH can be updated over I2C or with the on-board SPI connector.

The VHDCI connections can be used to interface with either non-buffered or buffered remote boards that distribute signals to neighboring modules. These modules can be assembled together and placed in COTS enclosures. The enclosures fit onto the low-cost and simple DIN rail standard.
