Description

The FMC156 is an FPGA Mezzanine Card (FMC) per VITA 57.1 standard, offering a small footprint and allowing for general-purpose I/O expansion.

The FMC156 provides eight M-LVDS input/outputs, sixteen RS-485 or eight RS-422 (per Port configurable), and twelve single-ended +3.3V/+5V GPIO.

The M-LVDS signals go through a Cross Bar Switch (CBS), which allows input/output routing within each group of eight M-LVDS signals. Each CBS port can be individually software-configured for routing, termination, and direction.

Each of the single-ended Ports can be configured as input or output and the I/O can be programmed to be either +3.3V or +5V (GPIO as a group are configured as +3.3V or +5V). The RS-485/422 configuration can be selected as full-duplex RS-422 (independent RX/TX pairs with RX termination) or half-duplex RS-485. If all Ports are configured as RS-422 only eight Ports are available. Each RX is programmable for termination.

The FMC156 can provide power of up to 12W to an external module.
