I have ordered the demo board. The problem is that the recommended parts such as X1 (ICM4712701) are no longer in production.

Better yet, a recommended ceramic resonator would be even better.&nbsp;</P><P></P><P>Thank you,</P><P>Rich</P></BODY></HTML> Mon, 16 Jul 2018 15:23:42 GMT richt1 2018-07-16T15:23:42Z sa606 https://community.nxp.com/t5/Other-NXP-Products/sa606/m-p/817642#M6294 <HTML><HEAD></HEAD><BODY><P>Hello,</P><P></P><P>I am trying to use the SA606D FM IF system in a new design.

Toko and other vendors have made many original adjustable shielded inductors obsolete due to low volume. Coilcraft may have a suitable replacement. Another solution is to use a fixed inductor and large capacitor in parallel with a smaller variable capacitor to provide tuning of the LC tank circuit for the demodulator.</P><P><BR />Have a great day,<BR />Pavel</P><P></P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
