DS15EA101 www.ti.com SNLS235H – SEPTEMBER 2006 – REVISED APRIL 2013 DEVICE OPERATION Input Interfacing The DS15EA101 accepts either differential or single-ended input. The input must be AC coupled. Transformer coupling is not supported. If the signal is differential, its amplitude must be 800 mVp-p ±10% (400 mV singleended). If the signal is single-ended, its amplitude must be 800 mV ±10%. Output Interfacing The DS15EA101 uses current mode outputs. They are internally terminated with 50Ω.
