TI公司的DSLVDS1047是3.3V LVDS四路高速差分线路驱动器,设计用于需要超低功耗和高数据速率的应用.采用低压差分信号(LVDS)技术,数据速率超过400Mbps(200MHz).DSLVDS1047采用低压TTL/CMOS输入电平,并转换成低压(350mV)差分输出信号,支持TRI-STATE功能,可以禁用输出级,禁用负载电流,因此使超低空闲电源功耗降低到典型的13mW(3.3V静态).工作电压3.3V,典型的差分抖动300ps,最大的差分抖动400ps,最大传输时延为1.7ns,±350-mV差分信令,满足或超过TIA/EIA-644 LVD标准,工业工作温度−40℃ 到+85°,主要用在多功能打印机,板对板通信,测试和测量,打印机,数据中心互连,实验室仪器和超声扫描仪.本文介绍了DSLVDS1047主要特性,功能框图,点到点应用框图以及评估板DSLVDS1047-1048EVM主要特性,建立配置图,电路图,材料清单和PCB设计图.

The DSLVDS1047 device is a quad CMOS flowthroughdifferential line driver designed for applications requiring ultra-low power dissipation andhigh data rates. The device is designed to supportdata rates in excess of 400 Mbps (200 MHz) usingLow Voltage Differential Signaling (LVDS)technology.

The DSLVDS1047 accepts low voltage TTL/CMOSinput levels and translates them to low voltage(350 mV) differential output signals. In addition, thedriver supports a TRI-STATE function that may beused to disable the output stage, disabling the loadcurrent, and thus dropping the device to an ultra lowidle power state of 13 mW typical. The DSLVDS1047 has a flow-through pinout for easy PCB layout.

The EN and EN* inputs are ANDed together andcontrol th..
