This • LVDS/CML/LVPECL Compatible Input, LVDS is especially significant when driving longer cables. Output The DS90LV804, available in the WQFN (Leadless • On-Chip 100 Ω Input and Output Termination Leadframe Package) package, minimizes the • 12 kV ESD Protection on LVDS Outputs footprint, and improves system performance. • Single 3.3V Supply An output enable pin is provided, which allows the • Very Low Power Consumption user to place the LVDS outputs and internal biasing • Industrial -40 to +85°C Temperature Range generators in a TRI-STATE®, low power mode. • Small WQFN Package Footprint The differential inputs interface to LVDS, and Bus LVDS signals such as those on TI's 10-, 16-, and 18- DESCRIPTION bit Bus LVDS SerDes, as well as CML and LVPECL. The DS90LV804 is a four channel 800 Mbps LVDS The differential inputs are internally terminated with a buffer/repeater. In many large systems, signals are 100 Ω resistor to improve performance and minimize distributed across cables and signal integrity is highly board space. This function is especially useful for dependent on the data rate, cable type, length, and boosting signals over lossy cables or point-to-point the termination scheme. backplane configurations.
