    TI Thinks Resolved
    Part Number: LMKDB1108 Other Parts Discussed in Thread: LMK1C1108 , Tool/software: Dear TI, looking at the jitter specifications reported in the datasheet , the LMK1C1108 has better jitter specification than LMKDB1108 (LMK1C1108: 20fs max/8fs typ @…

  • LMKDB1108: LOS# on LMKDB1108 not going low when input clock removed

    Part Number: LMKDB1108 Tool/software: I am not able to get LOS# to go low when the clock is removed from the input. 1) Are there any register bits that can mask an LOS# event? 2) Is there anything that can disable the LOS# function? Example -> vPWRGD…

  • LMKDB1108: Circuit Design Suggestion

    TI Thinks Resolved
    Part Number: LMKDB1108 Hi Experts, We are currently utilizing the LMKDB1108Z85RKPT and have incorporated a damping resistor solely on the input side, with no damping resistors added to the output side. The design is illustrated in the diagram below…

  • LMKDB1108: LMKDB1108 Single-Ended input and Reduced Output Voltage Swing

    TI Thinks Resolved
    Part Number: LMKDB1108 Tool/software: I would like to use the LMKDB1108 as a clock buffer in a non-PCIe application due to its very low power. I have couple questions: 1) Can the LMKDB1108 be driven single-ended from a LVCMOS 3.3V source with a resistive…
