has anyone ever been building FM transmitter using some one-chip solution? I was able to find the Si47xx transmitters, however they are NRND and cost about $15 each. Then there was the RDA5280 which can be bought for $2, however lacks RDS and is no longer manufactured. And the last option I found was the KT0803 (especially its L variant which has highest SNR) which is still manufactured, costs about $0.5, however doesn't have RDS compatibility.
Does anyone know of any other all-in-one chip which would include PLL, DSP core and mixers in one package? If possible, then also with RDS capability.
