    I’m doing project regarding HDB3 line cording, (High Density Bipolar 3) and I need to find a chip which function as HDB3 encoding and decoding. I have already found chips have this functionality. (zarlink product – MV 1449,MV 1442, MV 1471 ) http://category.alldatasheet.com/index.jsp?semiconductor=HDB3
    But unfortunately most of chips are obsolete.
    Could you mind please help me to find a chip that has above functionality?

    I'm also looking into this problem and I was wondering if anyone knows an specific chip that is not obsolete. Or is this encoding/decoding nowadays only implemented in asics?
