  LMK04805: 100ohm termination resistor

  TI Thinks Resolved

  Part Number: LMK04805 Hello, In LVDS mode of the LMK04805, If the receiver device has an internal 100 ohm termination resistor, is it okay to remove the external 100ohm termination resistor? Thank you. JH

  RE: LMK04805: Polarity discription mismatch of SYNC_TYPE between the data sheet and the clock tools

  Hi JH, I confirmed today that the datasheet is correct. TICS Pro is flipped. Regards,

  LMK04805: slow frequency swinging +-1..10Hz

  TI Thinks Resolved

  Part Number: LMK04805 We are using the LMK04805 with a CVHD950 122.88MHz VCXO and a 30.72MHz TCXO, then we set the output divider of clock out 0 to 1, so we have 2293.76MHz at the output. Phase noise looks ok above 10Hz. But on the spectrum analyzer we...

  LMK04805: LMK04805 Lock issue

  TI Thinks Resolved

  Part Number: LMK04805 Dears. We have used LMK04805. I am testing with LMK04805EVM. I entered 122.88Mhz into REF Clock(CLKin1) and set the GUI as follows. 122.88Mhz is supplied as a Signal Generator. Lock does not work. Why can not I lock? Thank y...

  RE: LMK04816: Generating 125 MHz and 150 MHz from the same LMK04816 part.

  Hi Doug, The least common multiple of 150 MHz and 125 MHz is 750 MHz, so you will need a multiple of 750 MHz to generate both frequencies. There is no multiple of 750 MHz in the 2370-2600 range. So your assumption is correct, the VCO range on the LMK04816...

  RE: CDCLVP1204 / CDCLVP1212 input edge rate question

  Hi Jaime Martin, Here is a better comparison. The reference is a 100 MHz WENZEL But to your point, you are absolutely correct. If you are driving LMK04805 PLL1 configured for relatively low bandwidth, the broadband noise floor is irrelevant. Either...

  RE: LMK048XX/049XX clock for RF DAC

  Noel, in this time we have changed our plans. We have now a frequency (around 2340 MHz) that needs the use, again, of LKM04805. But my main question is independent, I think, of that. Is it possible to use the LMK04805 in this "special" configuration...

  RE: LMK04805B loop filter

  Hi Nicolas, By permanent clocks if you mean clocks that are always active on start-up, then refer to the note below Before the LMK048xx is programmed, CLKout8 is enabled and operating at a nominal frequency (~90-99 MHz for LMK04805) and CLKout6 and...
