Looking for datasheet of HN16515 IC and Fun-Jin FT16-04B2 IC

Hello guys. I have got a couple of network adapters from which I have pulled out the 'isolation transformer ic'.
One is 'HN16515' (Unknown manufacturer)
and other is 'FT16-04B2' (FUN-JIN)

The problem is, I couldnt find any sort of data sheet of these components. All I need is their exact pinout. I have determined the functions of some pins by tracing their tracks to RJ-45 connector but I couldnt understand the function of other pins connecting to some other ic's on the card.

Plz tell me if any one has a idea or if someone could tell me their pin compatible ic's (whose data sheet is available)

Hello there,

I was also looking for HN16515 (10/100 Base-T Single Port Transformer) pin out and found the datasheet "mingtek.tw/pdf/B-2.pdf"

Have a PC motherboard onboard ethernet damaged by thunder of which the damaged part of the fast-ethernet transformer was suspected. Motherboard's ethernet transformer has different part number (16PT8515-4). Since the pin out and form size from the datasheet is the same, I'm looking forward to replace the supposely damaged part. This is just my story, nothing to do with what you seek :-D.

That fun-jin chip datasheet you're looking for is found with google too: "chinaicmart.com/series-FT1/FT16-04B2.html"

Hey, this board doesn't allow posting of link for new registrant below two post. So, just copy and paste the http links to get the datasheet info or search it yourself.
