Overview

The CDD-564AEN, CDD-564ALEN and CDD-562ALEN are our next generation integrated IP demodulators with 3xDES data decryption providing industry leading performance in a 1 RU package at a competitive price. They are designed to receive up to four independent 70/140 MHz or L-Band channels (depending on model) and combine the receive data into a single 10/100Base-T Ethernet port for transmission onto the LAN. The demodulators are designed to operate with Comtech EF Data’s CDM-570/L-IPEN and CDM-570A/L-IPEN IP-enabled modems with 3xDES encryption.
