DS91M124中文资料具有 LVCMOS 输入的 125MHz 1:4 M-LVDS 中继器数据手册TI规格书

描述 Description

The DS91M124 is a 1:4 M-LVDS repeater for driving and distributing clock or data signals to up to four multipoint networks.M-LVDS (Multipoint LVDS) is a new family of bus interface devices based on LVDS technology specifically designed for multipoint and multidrop cable and backplane applications. It differs from standard LVDS in providing increased drive current to handle double terminations that are required in multi-point applications. Controlled transition times minimize reflections that are common in multipoint configurations due to unterminated stubs.A single DS91M124 channel is a 1:4 repeater that accepts LVTTL/LVCMOS signals at the driver inputs and converts them to differential M-LVDS signal levels. It features independent driver enable pins for each driver output.The DS91M124 has a flow-through pinout for easy PCB layout. It provides a new alternative for high speed multipoint interface applications. It is packaged in a space saving SOIC-16 package.
