Single Clock Generator

  • Inquiry
  • Evaluation Board Manual
  • Data Sheet


The AK8119A is a single clock generator IC with an integrated PLL. It can generate either a 40.5MHz or 38.0MHz clock from a 12MHz master clock input frequency. Through pin control, the output can be enabled or disabled, and the frequency can be changed. The high performance PLL locks to the master clock input, generating a low jitter, highly accurate clock output without an external crystal.
