Part Number: LMX2571

I have choosing some programmable generator these days. I have to change the freq of the RF(around 433MHz) when it's working by SPI/ I2C.

Could this chip meet my requirements?

    Hi There,

    I am not clear what specific requirement you are looking for but here is a general answer.
    This device is programmable via SPI interface. If you want variable output frequency from time to time, you can keep programming the device to the desired frequency. If you want FSK, you can either program the device to the desired frequency deviation or you can feed the FSK data to the device via pins 4 to 7.
