Part Number: DAC3484EVM
I'm driving the J9 CLKIN input with a 153.6MHz LVPECL20 output from an LMK04828B_EVM CLKout0+/-. I've reduced the emitter resistance to 120 Ohms an have managed to get a 600mV signal riding on the 2V bias of the Primary clock input to the on-board CDCE62005 IC. I think I need help getting this CDCE62005 chip to operate. Upon powering up, the FPGA clock outputs to the J13 connector has a signal outputting from U3P/N outputs (i.e. Y3:FPGACLK1 on the CDCE62006 tab of the DAC3484EVM Software Control tab) so I know that the DAC3484EVM is operational and I've even run it connected to a TSW1400 and seen that work. I'm obviously doing something wrong but I don't know what. The CLKout0+/- is connected to an ADC-WB-BB balun. With or without the R1/R3 resistors, I'm not getting much of a difference in signal amplitude. Attached below is my setup for both cards. The LMK04828B_EVM is operational, but the DAC3484EVM is not seeing my clock input signal and producing the desired 131.072MHz output on U3P/N.
