NDR378: 6u VPX Digital Tuner

 

The NDR378 6U VPX digital tuner is an 8-channel, superheterodyne tuner that covers RF signals from 2 MHz to 6 GHz. It is a rugged 6U conduction cooled VPX module, per VITA 46/48/65/67. The NDR378 OpenVPX is designed as a 6U open architecture version of the existing NDR358 tuner to include RF performance, command set and all 4 DSP-based modes of operation. The NDR378 supports efficient system integration for existing NDR358 users. Integrated high dynamic range 16-bit Analog-to-Digital converters (ADC's) are utilized to digitize an 80 MHz wide IF at 256 Msps sample rate. Command and control of the digital tuner are via an Ethernet interface and power is derived from the P0 12V power supply input. Total power consumption is approximately 110 Watts. An on-board Xilinx Kintex UltraScale FPGA is used for the channelizer, the VITA-49 formatter, data multiplexer and the Digital IF data interface.
