SN65LVDS104D Datasheet PDF - TI

●The SN65LVDS104D is a 4-port LVDS and 4-port TTL-to-LVDS Repeater for use with network routers. The differential line receiver and a LVTTL input (respectively) connected to four differential line drivers that implement the electrical characteristics of low-voltage differential signaling (LVDS). LVDS, as specified in EIA/TIA-644 is a data signaling technique that offers low-power, low-noise coupling and switching speeds to transmit data at relatively long distances. The intended application of this device and signaling technique is for point-to-point baseband data transmission over controlled impedance media of approximately 100R. The transmission media may be printed-circuit board traces, backplanes or cables. Having the drivers integrated into the same substrate, along with the low pulse skew of balanced signalling, allows extremely precise timing alignment of the signals repeated from the input.
