2.0 DDC Hardware Interface
2.1 DDC General Specifications
The DDC module uses a Motorola 5282, 32-Bit processor core module with Ethernet on a Carrier PCA.
The Carrier PCA handles all power supply requirements and signal conditioning for the core processor
module. A Complex Programmable Logic Device (CPLD) is included on the carrier PCA to handle
logic and expansion. Serial ports are buffered on the carrier PCA and routed to the core processor mod-
ule.
General specifications are listed in Table 1
