1 PI9LV, PI9LVB LVDS Mux/Repeaer Feaures Mees or Exceeds he Requiremens of ANSI TIA/ EIA Designed for Signaling Raes up o 65 Mbi/s (5 MHz) Operaes from a.v Supply: 4 C o +85 C Low Volage Differenial Signaling wih Oupu Volages of ±5mV ino: - Ohm load (PI9LV) - 5 Ohm load Bus LVDS Signaling (PI9LVB) Acceps ±5mV differenial inpus Wide common mode inpu volage range:.v o.7v Oupu drivers are high impedance when disabled or when V CC.5V Inpus are open, shor, and erminaed fail safe Propagaion Delay Time:.5ns ESD proecion is kv on bus pins Bus Pins are High Impedance when disabled or wih V CC less han.5v TTL Inpus are 5V I/O Toleran Power Dissipaion a 4Mbi/s less han 5mW Indusrial emperaure raing Available Packaging: 6-pin SOIC and 6-pin TSSOP Descripion The PI9LV and PI9LVB are differenial line drivers and receivers ha use Low Volage Differenial Signaling (LVDS) o achieve signaling raes as high as 65 Mbps. The receiver oupus can be swiched o eiher or boh drivers hrough he muliplexer conrol signals S and S. This allows he flexibiliy o perform splier or signal rouing funcions wih a single device. The LVDS sandard provides a minimum differenial oupu volage magniude of 47mV ino a Ohm load and receip of mv DC signals wih up o V of ground poenial difference beween a ransmier and receiver. The PI9LVB doubles he oupu drive curren o achieve Bus LVDS signaling levels wih a 5 Ohm load. A doubly erminaed Bus LVDS line enables muli-poin configuraions. Swiching beween channels does no creae false ransiions on he oupus. The inended applicaion of hese devices and signaling echnique is for boh poin-o-poin base-band (PI9LV) and mulipoin (PI9LVB) daa ransmissions over conrolled impedance media.
