Other Parts Discussed in Thread: DAC5652, TRF372017

Hello,

Q1.- Is there any reference design to interface the DAC5652 and TRF372017 levels?

Q2.- In the TRF372017 datasheet "Figure 93. Block Diagram of the Baseband I Input Nodes" there is an external 100Ohms resistance for the diferential inputs. Is this resistance value mandatory or recommendable?

Thank you

    Hello,

    Please check out the following app note for some ideas on interfacing between DAC5652 and TRF372017

    http://www.ti.com/lit/pdf/slua647

    Please note it will be difficult to connect the two devices in DC coupled fashion due to the lower common mode voltage of the DAC5652. There will be loss associated with the level translation.

    We recommend placing external 100ohm at the baseband input for load termination. This improves the signal integrity of the baseband signal.
