Hi All, But I guess only Matt can answer this :-) What is the bandwidth of the PLL loop of the RFX1800 and the XCVR2450 ?
The XCVR2450 has a roughly 50 kHz loop bandwidth. The RFX1800 has about a 20 kHz loop bandwidth, but that will vary with settings. I suggest downloading ADISimPLL from Analog devices, and entering the values from our schematics if it is critical that you have control of the loop bandwidth on any RFX-series board.
