LVDS 2 Port High Speed Repeater
FIN1 102 LVDS 2 Port High Speed Repeater
January 2002
Revised February 2002
General Description
This 2 port repeater is designed for high speed interco nnects utilizing Low Voltage Differential Signaling (LVDS)
technology. The FIN1102 accepts and outputs LVDS levels
with a typical differential output swing of 330 mV which provides low EMI at ultr a low power dissipation even at high
frequencies. The FIN1102 provides a V
coupling on the inputs. In addition the FIN1102 can also
directly accept LVPECL, HSTL, and SSTL-2 for translat ion
to LVDS.

Note 1: The “Absolute Maximum Ratings”: are those values beyond which
damage to the device may occur. The databook specifications should be
met, without exception, to ensure that the system design is reliable over its
