I have read the datasheet of ADF4158/9 PLL Synthesizer IC.
The Synthesizer is capable of FSK and PSK modulations as wel.
In order to decide for this device, for my new design, I must know the maximum data rate supported by this device for FSK and/or PSK modulations.
The Datasheet says that "The PSK modulation is controlled by the TXDATA pin" (Page no. 26 of 36) but doesn't specify up to what data rate this pin can be fed with.
Could you please help provide the information about ADF4158/9?
