For simple TTL signals, we offer I/O cards with 8 channels over BNC or SMA connectors in the EEM form factor. 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. Outputs can supply 5V into 25Ohm, and can tolerate an indefinite short-circuit to ground.

For high-density or faster signals, DIO_RJ45 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 100Ohm loads (LVDS is short-circuit protected), inputs are 100Ohm 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.

Urukul is a 4 channel DDS-based frequency synthesizer for the EEM form factor. It provides sub-Hz frequency resolution, controlled phase steps, and accurate output amplitude control. We offer it in two variants, with either the AD9910 or the AD9912 chip.

+It is also possible to connect the Zotino using a HD68 cable to an external crate containing BNC-IDC cards.

Sampler is an 8-channel, 16-bit ADC EEM with an update rate of up to 1.5MSPS (all channels simultaneously). It has low-noise differential front end with a digitally programmable gain, providing full-scale input ranges between +-10mV (G=1000) and +-10V (G=1).
