• Spice model for ADCMP572 comparator

    Hi,

     I want to use ADCMP572 to have a square wave form at 1.2 GHz from a sin wave at the same frequency. Could ADCMP572 be used for this application and also is the a spice model available for ADCMP572?

  • ADCMP572 input signal pulse width issue

    Hi Analog Support Team,

     

    I have a question about ADCMP572 input signal pulse width.

    Per datasheet, it says 80ps minimum pulse width.

    Does it mean the comparator do not response to a input signal with a pulse less than 80ps?

     

    In the latch signal description…

  • AC coupled out from ADCMP572

    Does AC coupling the 8 Gbps CML output of a ADCMP572 SiGe comparator allow you to terminate the end of it's transmission line to a different voltage, e.g. 1.2V, than the Vcco of the ADCMP572 (3.3V)?

    Hi Joven, Thanks for the reply. We are using ADCMP572.

  • ADCMP572 ESD/differential input voltage spec

    Wondering if anybody could shed some light on:

    1) A rough idea about ADCMP572's input ESD spec (in 50 ohm environment without any additional ESD protection)

    2) Datasheet specifies ±1.2V input differential voltage range while the abs max spec is 

  • ADCMP572 can drive the load of 256pF?

    Will ADCMP572 can drive the load of 256pF? If not , which comparator can drive
    that capacitance?

     

    The comparator is built to drive 50 Ohm complex loads but doesn’t specify
    capacitive load capability.

    Basically, it will work, just…
  • ADCMP572 input signals' amplitude are reduced

    Hello,

    We have a problem with the ADCMP572. We desing the circuit according to figure 26 on the datasheet. (Please, see the attachement file.) also i added  the inputs and output signals osc displays.

    The problem is that the input signals' amplitudes…

  • ADCMP572 input termination absolute maximum rating?

    Hi,

    The datasheet for ADCMP572 curiously does not mention anything about maximum current/power in the input 50 Ohm termination resistors. For instance with VCCI=3.3 V, the other absolute max ratings seem to allow for input voltage to be as high as +3…

  • ADCMP572 output levels strange when input signal does not cross the threshold

    Dear all,

    We are using ADCMP572 circuit in our design to detect when an input oscillatory signal is crossing a threshold and to perform its 1-bit digitization. The output of the ADCMP572 circuit is connected to the high-speed differential receiver of…

  • What is the random jitter of ADCMP572 at lower slew rates than 5 V/ns (used for the datasheet jitter spec). In particular, what random jitter should I expect at 0.5 V/ns?

    (Oops, I'm a first time post-er here. I put it all in the title )

    This says it all:
