Is there a device which would accept differential LVPECL signal and convert it to differential signal of 6 v p-p or higher...
I am planning to adopt ADN2526 since it has open collector outputs...
My application requires such device with maximum propagation delay of 50ps.
The ADN2526 specs do not list propagation delay...
I apologize for the slow reply. Two devices come to mind: The ADCLK905, and any part in the AD9513/14/15 family.
The ADLCK905 will give you 2x the swing of an LVPECL driver, and is very fast.
The AD9513/14/15 have a CMOS mode where the differential pair can be out of phase. However, it's not as fast.
Hope that helps.
The ADCLK905 Paul suggested uses a state of the art SiGe process. It is only half as fast as what you want and the output swing is only about +-800mV.
I doubt that you will find anything that can get you a propagation delay of 50ps and deliver 6Vpp.
Just as a sanity check, if your rise time was 50ps on a 6V swing you would need to have 120mA of drive current per pF of load. And normally you want your rise time to be faster than your propagation delay. So this is REALLY hard.
ADN2526 takes a differential voltage modulation input in CML logic, converts this voltage signal to a modulated current sink signal with an internal 50 ohm termination. With a matched load (<50ohm), the max. Imodp/Imodn (compliance) voltage swing could be 2.2Vp-p. ADN2526 could support typ. 32pS, 20% to 80% edge time.
ADN2526 might not be the perfect device to satisfy your applications. What is the 6Vp-p logic signal compliant to? LVPECL or LVCMOS?
