HI-15530CLI 数据手册
HI-15530 Manchester Encoder / Decoder July 2001 GENERAL DESCRIPTION The HI-15530 is a high performance CMOS integrated circuit designed to meet the requirements of Mil-Std-1553 and similar Manchester II encoded, time division multiplexed serial data protocols. The HI-15530 contains both an Encoder and Decoder, which operate independently. The device generates Mil-Std-1553 sync pulses, parity bits as well as the Manchester II encoding of the data bits. The decoder recognizes and identifies sync pulses, decodes data bits, and performs parity checking. The HI-15530 supports the 1Mbit/s data rate of Mil-Std1553 over the full temperature and voltage range. For applications requiring small footprints and low cost, the HI-15530 is available in a 24-pin plastic SOIC package. Ceramic DIP and LCC packages are also available to achieve the highest level of reliability and to provide drop-in replacement for obsolete parts from other manufacturers. FEATURES !

An auxiliary divide by six counter is provided on chip which can be utilized to produce the SEND CLOCK by dividing the ENCODER CLOCK. The Encoder's cycle begins when ENCODER ENABLE is high during a falling edge of ENCODER SHIFT CLOCK (1). This cycle lasts for one word length or twenty ENCODER SHIFT CLOCK periods. At the next low-to-high transition of the ENCODER SHIFT CLOCK, a high at SYNC SELECT input actuates a command sync or a low will produce a data sync for that word (2). When the Encoder is ready to accept data, the SEND DATA output will go high and remain high for sixteen ENCODER SHIFT CLOCK periods (3). During these sixteen periods the data should be clocked into the SERIAL DATA input with every low-to-high transition of the ENCODER SHIFT CLOCK (3) - (4). After the sync and the Manchester II coded data are transmitted through the BIPOLAR ONE and BIPOLAR ZERO outputs, the Encoder adds on an additional bit which is the parity for that word (5). If ENCODER ENABLE is held high continuously, consecutive words will be encoded without an interframe gap. ENCODER ENABLE must go low by time (5) as shown to prevent a consecutive word from being encoded. At any time a low on the OUTPUT INHIBIT input will force both bipolar outputs to a high state but will not affect the Encoder in any other way. To abort the Encoder transmission a positive pulse must be applied at MASTER RESET. Anytime after or during this pulse, a low to high transition on SEND CLOCK clears the internal counters and initializes the Encoder for a new word.

The Manchester II coded data can be presented to the Decoder in one of two ways. The BIPOLAR ONE and BIPOLAR ZERO inputs will accept data from a comparator sensed transformer coupled bus as specified in MIL-STD-1553. The UNIPOLAR DATA input can only accept non-inverted Manchester II coded data (e.g. from BIPOLAR ZERO OUT of an Encoder). The Decoder is free running and continuously monitors its data input lines for a valid sync character and two valid Manchester data bits to start an output cycle. When a valid sync is recognized (1), the type of sync is indicated on COMMAND/DATA SYNC output. If the sync character was a command sync, this output will go high (2) and remain high for sixteen DECODER SHIFT CLOCK periods (3), otherwise it will remain low. The TAKE DATA output will go high and remain high (2) - (3) while the Decoder is transmitting the decoded data through SERIAL DATA OUT. The decoded data available at SERIAL DATA OUT is in a NRZ format. The DECODER SHIFT CLOCK is provided so that the decoded bits can be shifted into an external register on every low-to-high transition of this clock (2) - (3). After all sixteen decoded bits have been transmitted (3) the data is checked for odd parity. A high on VALID WORD output (4) indicates a successful reception of a word without any Manchester or parity errors. At this time the Decoder is looking for a new sync character to start another output sequence. VALID WORD will go low approximately 20 DECODER SHIFT CLOCK periods after it goes high if not reset low sooner by a valid sync and two valid Manchester bits as shown (1). At any time in the above sequence, a high input on DECODER RESET during a low-to-high transition of DECODER SHIFT CLOCK will abort transmission and initialize the Decoder to start looking for a new sync character.
