Is it possible to connect more than one AD9265 on the same LVDS bus?

 

In general, an LVDS is meant to be a point-to-point interface (i.e. only one
driver and receiver on each link).  Adding additional loads onto the same link
causes signal integrity issues since the LVDS line will not be properly
terminated (with multiple reflections due to multipoint PCB traces). 
Perhaps another option is to use a high speed serial output ADC like the AD9253
quad ADC (14-bit, 125 MSPS). 
While SNR in not as good as AD9265 (out by 5 dB)...........perhaps it is still
considered sufficient for the application and allows a lower pinout interface
to FPGA.
