Hello, somewhere in the data sheet is told that an external reference signal can be applied at CC2510 XOSC-Q1 instead the crystal itself in Q1/Q2.
In this case is there any data about the drive level, and input impedance of the external reference input at Q1?
We are designing a quadruple reader and I would like to drive 4 CC2510 from a single 26 MHz TCXO, because this way I can synchro perfectly the 4 transceivers, otherwise, I would need 4 independent crystals and apart from the sync, maybe this solution can be more sensitive to RF crosstalks. The TCXO device I plan to use delivers 0.8Vpp on a 10Kohm, 10pF load with DC coupling. I would like to know if this device is suitable to drive 4 CC2510 either directly or using 4way small signal distribution
Thanks in advance
