• RE: AD9515 Clock Input general questions

    Hi,

    in the future, you should post questions related to clocking ICs in the Clock and Timing section of Engineer Zone:https://ez.analog.com/clock_and_timing

    As you said, the AD9515 is a clock distributor chip. It needs a clock at the input. It does not…

  • AD9515

    Hi, I want to use AD9515 as clock driver to AD9230. According to the spec of AD9515, the low level of clock output is 3.3-1.76=1.54V for LVPECL and 1.0V for LVDS. However, AD9230 recognizes clock as low only when the voltage is below 0.8V. I dont understand…

  • Smartest way to include setup pins jumpers of AD9515 in PCB

    Hello dear community,

    I'm using AD9515 clock divider IC to feed an ADC. 

    There are 10 setup pins with 4 possible configurations for each of them (Vs, 2/3Vs, 1/3Vs, GND).

    I was wondering what was the best way to have a reconfigurable pins without turning…

  • AD9515 input

    Can anybody suggest a part that can convert 200mVp-p/100MHz Sinewave generated from OCXO to LVCMOS digital clock signal/100MHz? The output dutycycle should be 45-55% and jitter should be less than 50ps.

    Can I use AD9515 clock divider for this application…

  • AD9515 output disable

    Hi,

    I'm using AD9515 in our design and using the OUT0 as LVPECL and OUT1 as CMOS.

    But I'm using only one CMOS output of OUT1. The other output is not used.

    How should I connect this pin to avoid radiation? I assume that if left open this pin can…

  • AD9515 Phase Start High

    Hi, could someone please explain the difference between "Phase" and "Phase (Start High)" options in Table 14 in the AD9515 Datasheet?

    Thank you.

  • AD9515 Power requirements

    I will be using AD9515 as clock divider for a part that is 10MHz-1GHz synthesizer with LVPECL and LVDS up to 1GHz and LVCMOS up to 250MHz. How can I estimate the power requirement (max.current draw) for the AD9515?

  • AD9515 Slew Rate minimum Requirement

    i'm going to use AD9515 chip in my design for converting 100MHz signal to 10MHz signal
    Slew Rate calculation: for 100MHz 1 cycle time will be 10ns. So, if i divide it by 4 maximum peak voltage point can be obtained at 2.5ns.
     
    I'm providing the input…
  • using AD9515 for making coincident IO_UPDATE signals

    Hi everyone,

    I want to synchronize two AD9915 DDS according to AN-1254 document. In this document AD9515 is used for distributing IO_UPDATE to DDS ICs. It is indicated in the document, IO_UPDATE signals should be coincident for two DDS ICs at the last…

  • AD9515 Setup pin(S0-S10)equivalent circuit

    See datasheet Figure 28,the equivalent circuit Resistance is inside in AD9515?
