安森美半导体推出新的时钟和数据多工器产品,优化实现高速、低功耗设计  Japanese Korean

新器件满足更快数据速率、更高时钟频率而无损信号完整性的要求

New Clock and Data Multiplexer Devices2010年4月26日 – 应用于绿色电子产品的首要高性能、高能效硅方案供应商安森美半导体(ON Semiconductor,美国纳斯达克上市代号:ONNN)进一步扩充多工器产品阵容,新推出NB6VQ572MNB6LQ572NB7L572NB6L572MNB7LQ572NB6LQ572MNB7VQ58MNB7V58M多工/扇出器件,可在高输入速率/时钟频率下工作。这些新器件均适用于SONET、千兆以太网、光纤通道、背板及其他时钟/数据分配应用。

NB6VQ572M和NB6LQ572M高性能差分4:1时钟/数据输入多工器带有1:2电流模式逻辑(CML)时钟/数据扇出缓冲器,运行电源电压为1.8 V、2.5 V或3.3 V,工作速率高达 6 GHz/8 Gbps。新器件具有小于10 ps的数据相关抖动,以及小于0.8 ps RMS的随机时钟抖动。

NB7L572和NB6LQ572高性能差分4:1时钟/数据输入多工器具有1:2的低压正射极耦合逻辑(LVPECL)时钟/数据扇出缓冲器。该器件的差分INx/Inxb输入包括内部50 Ω(欧姆)终端电阻,并可接受差分LVPECL、低压差分信号(LVDS)或CML逻辑电平。同时,这些器件还集成了一对可选引脚,可以从4个差分输入中选择其一,并为速率高达7 GHz/10 Gbps的时钟或数据产生两个相同的LVPECL输出备份。NB6L572M和NB6LQ572M补充了该产品阵容。前者拥有1:2的CML时钟/数据扇出缓冲器,运行速率高达6 GHz/8 Gbps;后者支持相同的速度,但每一个输入对都集成了一个固定均衡器接收器,以提高通过FR4 PCB背板或电缆互连传输的降级信号。

NB7VQ58M高性能差分2:1时钟/数据多工器也有一个可选的均衡器接收器。当与运行速率高达10.7 Gbps的数据路径串联时,它可以补偿降级信号,创造一个更加开放的眼图,实现标准FR4上的更高数据速率。NB7V58M 2:1时钟/数据多工器的差分输入集成了内部50 Ω终端电阻,通过VT引脚进入。这个特性让器件可接受LVPECL、CML和LVDS逻辑电平标准。NB7V58M的时钟/数据抖动最小,并可在7 GHz/10.7 Gbps的速率下工作。每个器件的工作温度范围均为-40 ⁰C至 +85 ⁰C。

安森美半导体时钟和数据管理产品总监Prescott Sakai 表示:“工程师期望实现更高的时钟速度和数据速率,但又须确保无损信号完整性。这些新的时序器件支持现代系统设计需要的高速数据速率,同时保持低抖动,并补偿信号损失。”

封装及价格
NB6VQ572M、NB6LQ572、NB7L572、NB6L572M、NB7LQ572和NB6LQ572M均采用5 mm x 5 mm QFN-32封装。NB7VQ58M和NB7V58M采用扁平3 mm x 3 mm QFN-16封装。这些器件每1,000片批量的价格为6.5美元。
