  Shawn Han

  Hi Weida, Can you share your LMK61E07 schematic with power supply ? Just want to check if there are other causes. I can expect there is some spurs related with I2C clock, but do not expect there is such worse phase noise degraded. Regards, Shaw…

  Weida Zhang

  Thanks Shawn. Have you got an optimised filter setting which we can try on LMK61E07? We found that the filter works on LMK61E2 usually sends LMK61E07 out of locked. The LMK61xx Oscillator Programming Tool doesn't seem recognising LMK61E07 and mistakes…

• RE: TRF3765: 900 MHz synthesizer needed OTP

  

  Arvind Sridhar

  Hi Amr, We do not have Synthesizers in our portfolio with integrated EEPROM/OTP. However, you could potentially evaluate a clock generator like LMK003318 or Oscillator like LMK61E07 that can output 900 MHz (Square wave - LVPECL, LVDS, CML levels).
