FIN1108T (RT) features Internal Termination ResistorsApplicationFor LVDS signaling in point-to-point applications, receivers or repeaters with on-chip termination are preferable to reduce the overshoot or undershoot due to the reflection caused by stubs at receiver inputs. As a rule of thumb, usually the termination resistor for an LVDS receiver should be placed as close as possible to the receiver, especially for high speed applications. If the distance between termination resistors and receivers is too long, the interconnection will be seen as an un-terminated stub which can produce reflections resulting in higher EMI. Internal termination can effectively smooth out this ringing which can otherwise jeopardize the receiver noise margin. This is important for reliable high-speed operation with tighter required signal settling times. Below is a list of the advantages/disadvantages of internal termination.
Internal termination is not suitable for all applications. In order to set a proper VOD at the driver outputs, receivers with on-chip termination resistors only work for point-topoint applications since multi-drop applications would require termination resistor for each receiver, reducing the equivalent termination to RT/n. This would reduce the driver output swing by n.

The FIN1108 accepts and outputs LVDS levels with a typical differential output swing of 330mV, which provides low EMI at ultra-low power dissipation even at high frequencies. The FIN1108 provides a VBB reference for AC coupling on the inputs. In addition, the FIN1108 can directly accept LVPECL, HSTL, and SSTL-2 for translation to LVDS.
