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.
