Hello,
I am using ds92lv1021, ds92lv1212 sedes for module communication. SERDES(DS92lv1021, DS92lv1212) is placed on the PCB. This PCB is getting Power, clock and other signals from FPGA Evaluation Kit (SP601, spartan-6) through FMC connector. CLock is also derived from the FPGA. Clock and all other signals are fed to SERDES through Voltage Translator (2.5 V to 3.3 V).
Now the problem is,,,, whenever i connect oscilloscope or multimeter ( floating) ground connector to my setup ground,,,, some sort of garbej data is received .... if i keep the connector attached with the setup, garbej data is not further received . why is this happening??
