Digital / Analog Products

Control PCB is Virtex 6 based custom IO board designed to meet the customer’s specific requirement. Control PCB provides 2M x 36 bit of SRAM as a system memory and 256Mb of flash memory as Configuration/application memory. Control PCB supports two Gigabit Ethernet ports, one USB-UART port, twenty two pairs RS-422 compatible IO lines, twenty four pairs of LVDS outputs, eight single ended or four differential analog inputs, accelerometer, on-board and on-die temperature measurement interface and load current measurement interface.

This VME based slave card capable of Interfacing to two External Primary Radar Sources and two External Secondary IFF Sources.

Primary Analog:

Primary Analog video inputs (LIN/LOG/MTI) from the two radar sources shall be adjusted for gain and offset using front panel potentiometers. Then the Primary Video signals shall be scaled down to and given out on VME-P2 connector to the next card in the system.

Secondary Analog:

Secondary Analog Video inputs (IFF) from two radar sources shall be adjusted for gain and offset using front panel potentiometers. Then the Secondary Video signals shall be scaled down to and given out on VME-P2 connector to the next card in the system.

Digital inputs:

Digital inputs from the primary radar sources, namely ACP, SHM and SYNC shall be conditioned by means of protection, pulse discrimination and validation. Then the buffered Digital signals shall be passed out VME-P2 connector.

Video signals and Digital signals shall be fed back to the card after being routed in another associated card of the system. The card shall conduct POST by comparing the looped back signals and the input signals. The card shall also conduct on-line diagnostics by comparing the looped back signals and input signals. Hence, the Card operates in three modes: POST, Normal and On-Line Diagnostic.

Control and software programmability by the host is through VME interface, since this card would be used in a VME back plane in combination with other associated cards.

The RVIF Board is mainly used in Radar Systems for communicating two signals. The board has two channels namely channel 1 and channel 2 for communicating signals with the radar.

On-board features include 1 Megabit (128 K x 8-Bit) Uniform Sector Flash memory, 1K (128x8) SPI Serial EEPROM, In-System Programmable Configuration PROM, High performance Spartan-IIE Xilinx FPGA which has densities ranging from 71,000 to 2,00,000 system gates and System performance is supported beyond 200 MHz, High performance CPLD which has 288 macro cells with 6,400 usable gates and system frequency up to 208 MHz.
