• 关于AD9148芯片吞吐量问题

    您好,

    AD9148是支持四通道的。

    如果四个通道同时用,最高支持4GSPS,还是四个通道总共1GSPS?谢谢

  • RE: One DPG 3 to drive 2 DAC AD9122

    Hi Chris,

          I am wondering if you can use quad DAC evaluation board instead of two AD9122 boards. Not so sure if you have other specific requirements, like data rate(245.76M?), interpolation(4?), DAC clock rate and so on. if quad DAC, like AD9148/AD9144…

  • RE: 最近调试一个项目芯片的输入信号要用到I/Q差分输入信号,由于设备限制不能产生I/Q差分输入信号,看看谁有好的建议!

    您好!

    您是想产生I/Q信号,还是已经有了IQ信号需要把IQ信号转换成差分的信号?

    如果是想产生差分信号作为IQ调制器的输入,可选用高速DAC产品,如AD9122,AD9148等,也可选用数字正交调制芯片产生,如AD9957。

    如果已经有IQ信号想转换为差分形式,通常可选用巴伦,射频变压器和差分放大器来实现。需要根据信号工作频率,前级和后级所需的驱动能力等进行选择。

    There are mainly two interface clocking schemes in the high speed DACs, source synchronous + FIFO scheme and data clock out (DCO) + input data scheme.
