• LMK04826: LMK04826-EP issues at temperature

  

  Marcio Koptcke

  Resolved

  Part Number: LMK04826 We are running into a frequency offset at hot that can be traced to the TI part LMK04826-EP. Basically, the issue is that when the radio reboots when it's hot, the PLL cannot lock. It locks once the temperature decreases enough…

• LMK04826: PLL1 cannot be locked

  

  xu lang

  Part Number: LMK04826 Tool/software: This is my configuration. The goal is to use LMK04826 to eliminate jitter. After power supply, LMK04826 cannot lock, and the output frequency is around 99.9997MHz. May I ask what problems need to be investigated
