I am trying to use the SA606D FM IF system in a new design. I have ordered the demo board. The problem is that the recommended parts such as X1 (ICM4712701) are no longer in production. Furthermore, I cannot even find a datasheet so someone else can make an equivalent. Also, Toko has stopped making inductors and a recommended replacement for IFT1 would be helpful. Better yet, a recommended ceramic resonator would be even better.
