Single Clock Generator

  • Inquiry
  • Data Sheet


The AK8128D is a single clock generator IC with an integrated PLL. It can generate a clock for High-Definition display from a 27MHz or 48MHz master clock input frequency. A high performance PLL locks to the master clock input, generating a low jitter, highly accurate clock output without an external crystal.
