  1. Will the 5PB11xx (5PB1102, 5PB1104, 5PB1106, 5PB1108, 5PB1110) buffers be able to drive 1PPS

    Hi, I am planning to use 5PB1104 for 1PPS signal fanout since DS specifies Input Frequency as 0 to 200MHz and Duty cycle on outputs will match incoming clock duty cycle. Is that OK?

  2. 5PB1102 and 5PB1108 fanout clock buffer ESD parameter

    Hi  all       Recently, i choosed the 5PB11XX series LVCMOS  clock buffer for fanout use. However,datasheet makes no mention of what kind of ESD input protection the chip has.  I want to inquire about the ESD parameters of this chip.Thanks.

  3. Will the 5PB11xx (5PB1102, 5PB1104, 5PB1106, 5PB1108, 5PB1110) buffers be able to drive a pulse signal?

    Will the 5PB11xx (5PB1102, 5PB1104, 5PB1106, 5PB1108, 5PB1110) buffers be able to drive a pulse signal? What would be the minimum pulse width and the pulse repetition frequency that these parts can support?
