HD-15531/883 is a Manchester Encoder-Decoder chip produced by Intersil, which supports MIL-STD-1553, and supports 1.25Mbit/s and 2.5Mbit/s data rates, supports data lengths from 2 to 28 bits, and has low power consumption.
The Intersil HD-15531/883 is a high performance CMOS integrated circuit intended to service the requirements of MIL-STD-1553 and similar Manchester II encoded, time division multiplexed serial data protocols. The device consists of two independent sections: an Encoder that produces sync pulses, parity bits, and encodes data, and a Decoder that recognizes sync pulses, identifies them, decodes data bits, and checks parity.
