SCDCT2512 Rev E
DESCRIPTION
The Aeroflex-Plainview CT2512 contains 2 Transceivers, 2 Encoder/Decoders, Bit Processors and complete
Remote Terminal (RT) logic. The device is constructed using Aeroflex advanced VLSI custom chip and hybrid
technology. It functions as a complete dual redundant MIL-STD-1553B RT Unit supporting all 13 mode codes for
dual redundant operation. The CT2512 is a pin-for-pin functional equivalent of the DDC BUS-65112/117 and
performs parallel data transfers with a DMA type handshake. Multiple error flag outputs and host access to many
of the RT Status Word bits are just some of the features that make this part ideal for many RT applications. The unit
has an operating range of -55°C to +125°C. See "Ordering Information" (last sheet) for CT2513 / CT2510 /
CT2511.
