-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.

+##### Sinara 2245 16-channel non-isolated LVDS RJ45 TTL card
+
+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.

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.
