The HD-15530 is a high performance CMOS device from Intersil that is intended to service the requirements of MIL-STD-1553 and similar Manchester II encoded, time division multiplexed serial data protocols. This LSI chip is divided into two sections, an Encoder and a Decoder. These sections operate completely independent of each other, except for the Master Reset functions. This circuit meets many of the requirements of MIL-STD- 1553. The Encoder produces the sync pulse and the parity bit as well as the encoding of the data bits. The Decoder recognizes the sync pulse and identifies it as well as decod- ing the data bits and checking parity. This integrated circuit is fully guaranteed to support the 1MHz data rate of MlL-STD-1553 over both temperature and voltage. It interfaces with CMOS, TTL or N channel support circuitry, and uses a standard 5V supply. The HD-15530 can also be used in many party line digital data communications applications, such as an environmen- tal control system driven from a single twisted pair cable of fiber optic cable throughout the building.
The HD-15530 provides both encoding and decoding of Manchester‑II coded data for MIL‑STD‑1553 applications. It includes separate encoder and decoder sections, a master reset function, and supports both bipolar and unipolar input configurations.
