It's not clear what you want.  If you just want to convert the serial bit 
stream to a parallel bit stream then a couple of shift registers and a 
PAL will do it much cheaper than anything with a Sony label on it.

If you want to convert the serial bit stream into a pair of analog 
channels then Sony makes a couple of chips.  Call Sony at (201) 368-5020 
for more information.  I have in front of me a "Sony Semiconductor Product
List" from January 1985 that lists a number of Serial D/A converters.  For 
example the CX20152 is a dual 16 bit 88khz multiplexed D/A.   This part 
a year or two ago had a price of $25 (I forget the quantity.)

Cheers.
