ULATION bits, the VCO frequency is instantly updated. An arbitrary frequency modulation can then be performed dependant

only on the rate at which values are written into the FMOD register.

The modulation frequency is calculated according to the following formula:

Where MODULATION is a 2's complement number and FPD is the phase detector frequency.

Programming Information

The RFFC5071 and RFFC5072 share a common serial interface and control block. Please refer to the Register Maps and Pro-

gramming Guide which are available for download from http://rfmd.com/products/IntSynthMixer/.

Evaluation Boards

Evaluation boards for RFFC5071 and RFFC5072 are provided as part of a design kit, along with the necessary cables and pro-

gramming software tool to enable full evaluation of the device. Design kits can be ordered from www.rfmd.com or from local

RFMD sales offices and authorized sales channels. For ordering codes please see “Ordering Information” on page 26.

For further details on how to set up the design kits go to http://rfmd.com/products/IntSynthMixer/.

The standard evaluation boards are configured with 3.7GHz ceramic baluns on the RF ports and wideband transformers on the

IF ports. On the RFFC5071 evaluation board, mixer 1 is configured for down-conversion and mixer 2 is configured for up-con-

version. On the RFFC5072 evaluation board, mixer 2 is configured for down conversion.
