Does anyone know the correct part number for the U1 IC on the board.  What appears to have been some static charges seems to have damaged the differential receiver chips on 3 of my receivers and I would rather replace them then buy a whole new board at over $30 a piece plus shipping.  The SA32A part number on the chip does not produce any results in any searches but there are plenty of TI chips associated with this that are in stock but I don't know which one if any to order.  I currently have 10 of these boards and 3 of them are down.  1 is down 1 port and another is down 2 and the 3rd has no data at all but if I press the test function, all three of them light the nodes on all ports.  I know that there is no issue with the RJ45 jacks or the cable so if any one can help with a part number, it would really be appreciated.
