• Do you have any examples with maximum distance achieved for the isolated LVDS with the ADN4651?

    Do you have any examples with maximum distance achieved for the isolated LVDS with the ADN4651?

  • RE: 4/26/16: Ubiquitous Measurement and Control with LVDS Isolators

    The primary difference between ADN4650 and ADN4651/ADN4652 is the channel directionality. ADN4650 has two isolated LVDS channels in the same direction (two transmit or two receive channels). ADN4651 or ADN4652 by contrast have one channel each direction…

  • RE: 4/26/16: Ubiquitous Measurement and Control with LVDS Isolators

    ADN4650/ADN4651/ADN4652 isolation implementations benefit from being fully differential throughout, including external LVDS board traces, the integrated LVDS I/O, and indeed the ADN4650/ADN4651/ADN4652 isolation transformers and circuitry. This greatly…

  • RE: 4/26/16: Ubiquitous Measurement and Control with LVDS Isolators

    ADN4650/ADN4651/ADN4652 devices include an integrated LDO so that the part can be supplied from a 3.3V rail. The isolator and LVDS I/O operate from the LDO’s 2.5V output, or can be supplied directly from a 2.5V supply in the system.  Galvanic isolation…

  • RE: 4/26/16: Ubiquitous Measurement and Control with LVDS Isolators

    The ADN4650/ADN4651/ADN4652 include fully LVDS compliant outputs, ensuring a differential voltage of typically 350 mV when terminated with a standard 100 Ohm load. At high data rates, the limiting factor for cable length becomes the jitter acceptable…

  • RE: 我最动芯的ADI新品评选

    ADN4651这款新品颠覆了我对数字隔离器速度和抖动的常规理解。现在我用的ADI公司的标准数字隔离器中,速度最高的是150Mbps,抖动指标实测在200ps左右,使用起来很顺利,各项参数都很稳定,本以为足够一段时间使用了,突然项目需要一个能传输400Mbps信号的LVDS收发器,正愁找不到合适芯片的时候,发现ADN4651竟然支持600Mbps,且抖动降低到70ps,在心中窃喜的同时,也有点顾虑:按照ADI公司以往产品介绍资料,采用传统编解码方式的架构是不能支持150Mbps以上速率信号的传输的…

  • RE: Understanding pulse width distortion and minimum pulse width requirement

    Hans,

    You might also consider the ADN465x family. The maximum pulse skew is 100 ps on a given channel, and 300 ps channel to channel for the ADN4650 (500 ps for the ADN4651/52). There is a power trade-off since this family is designed to operate at much…

  • How can I provide an isolated clock to AD9954?

    Now I need an  an isolated REFCLK to AD9954, but I couldn't find any Standard Digital Isolators suit for 400MHz operation. So i turn to LVDS isolator which could probide up to 600MHz isolation. However, i face a problem about REFCLK input voltage swing…

  • DOES ADN4650 ISOLATOR must be inputted NRZ data?

    ADN4650 datasheet中提到了,其能接收600Mbps的NRZ数据,那么是否说,非NRZ的差分数据,这款芯片没法正常工作?
    我们预期使用这款芯片进行视频数据的隔离。如果必须得是NRZ数据,那么这是由于icoupler技术本身的限制,还是别的?我看ADI这边像I2C ,SPI等的icoupler器件都可以的,没有说需要NRZ。望解答,多谢您;

  • RE: board layout for rj45 shield when using adn4652

    Hi,

    Your cable shield (or shields) should be earthed. There are different RJ-45 connector footprints (e.g. surface-mount vs. through-hold, different shield connections) but in general it should be possible to connect the shield of the connector (connects…
