Project title “Analog to Ethernet Converter”

Project Sponsor: 3dB Labs, Inc. Dayton Ohio

The device will digitize fairly wideband data and convert the data into UDP (User Datagram Protocol) packets to send over gigabit Ethernet.

Design Specifics:

• 4 or more DDC (Digital Downconverter) channels, each feeding a separate 1gbe NIC (Network Interface Card) with a different frequency band of the digitized signal
• each channel supporting ~20MHz bandwidth
• 14-16 bit ADC, 16 bit samples
• external connector for a clock reference that drives the ADC e.g. 10MHz
• external connector to accept precision timecode signal (e.g. IRIG-B for high precision time synchronization) into the digitized data , e.g. in packet headers or least significant bits
• good shielding
• fairly low power, e.g. <10 W per gigabit "channel"
