Minimum component count application circuit

The TDA 5150 application circuit shown demonstrates the ease and simplicity of an

intelligent transmitter implementation. The µC configures the TDA5150 via 3-wire SPI,

the SDIO line is used at the same time to transfer data on SPI bus and as digital data

input into the RF modulator. The CLKOUT line may be used as clock source for the µC

or as a timer for bitrate generation.
