Other Parts Discussed in Thread: LMK04828,
Hi Jim,
Thank you for your response. I checked the EVM schematic. In that they are doing ac-coupling. 'CLKP' and 'CLKN' going to DAC from LMK04828 are ac coupled (C340 and C341). There is a 121ohm termination used on both P & N lines before the capacitor (R179, R180).
LMK04828 datasheet says that the LVPECL differential output is 1600mVpp. But DAC37J84 datasheet says that the Vcm is 0.5V and max p-p clock is 800mV. From the look of it, both of these levels doesn't match.
Hence I am not able to understand how the above EVM schematic satisfies this requirement of DAC.
Regards,
Kiran
