• AD9508 clock input

    Hello,

    I would like to use the AD9508 with a sine wave input, but it is not clear from the datasheet if this is possible.

    Does the AD9508 support such inputs, or do they have to be a square wave?

    Thank you in advance,

    Yulia

  • AD9508/PCBZ API

    I have a system that uses the Analog Devices AD9508/PCBZ eval board to route clocks to various sinks.  It takes a 150 MHz input clock and provides the following:

    • 2x LVDS 150 MHz clocks
    • 2x 10 MHz CMOS clocks
    • 2x 50 MHz CMOS clocks

    The output format…

    Dear Analog Devices

    I am having challenge in clarifying some details regarding the use of the AD9508.

    My intention is to implement the clock fan-out buffer towards three ADV7180 analog video decoders. I suggest to use a 57.2727MHz (+/-25ppm) oscillator…

  • Problems wih AD9508 cmos output

    Hi,

     I need 8 single-ended 100MHz clocks  and these are have same frequency and phase. I see  AD9508 have  8 1.8V CMOS outputs. The problem as follows,

    1. I see in the datasheet of AD9508 in page 26 rev .G , look at the red line in the picture below. In "PIN…

  • AD9508 OUTPUT 1.8V CMOS question

    Hi

       I am debugging the function of AD9508. I have configured it in pin programming mode (AD9545 datasheet Pg26), but why the output is 2V level CMOS, which is theoretically 1.8V.

       

  • AD9508: Pin Strapping resistor values

    Hi All

    In the course of reducing the parts count of our Mainboard, I'd like to change the pin strapping resistors for the AD9508 from 820R to 1K. Will the corresponding function be correctly selected anyways? Or is it necessary for the resistors to match…

  • AD9508 cmos output problem

    Hi all,

         We use AD9508 to generate 40M clock signal.Now we have two questions:

    1,The  low level of clock waveform  is 500-600mv.It can not  get close to 0mv;Is there a problem?How to solve it?

    2,The clock waveform of 40M is not same as  figure 12 of the AD9508…
