SCAN90004中文资料具有预加重功能的 4 通道 LVDS 缓冲器/中继器数据手册TI规格书

描述 Description

The SCAN90004 is a four channel 1.5 Gbps LVDS buffer/repeater. High speed data paths and flow-through pinout minimize internal device jitter and simplify board layout, while configurable pre-emphasis overcomes ISI jitter effects from lossy backplanes and cables. The differential inputs interface to LVDS, and Bus LVDS signals such as those on TI's 10-, 16-, and 18- bit Bus LVDS SerDes, as well as CML and LVPECL. The differential inputs and outputs are internally terminated with a 100Ω resistor to improve performance and minimize board space. The repeater function is especially useful for boosting signals for longer distance transmission over lossy cables and backplanes. Integrated testability circuitry supports IEEE1149.1 (JTAG) on single-ended LVTTL/CMOS I/O and limited IEEE1149.6 capability on high-speed differential LVDS interconnects. The 3.3V supply, CMOS process, and LVDS I/O ensure stable high performance at low power over the entire industrial -40 to +85°C temperature range.
