PRODUCTION DATA.
Figure 48 shows the equivalent circuit of each LVDS output buffer. After reset, the buffer presents a 100-Ω output impedance to match the external 100-Ω termination.
The VID voltage is nominally 350 mV, resulting in an output swing of ±350 mV with 100-Ω external termination. The buffer output impedance behaves in the same way as a source-side series termination. By absorbing reflections from the receiver end, the buffer helps improve signal integrity.
