Description
The AK8141 is a single clock generator IC with an integrated PLL. It can generate a 27.0MHz – 50.0MHz by 1MHz step or 33.75MHz, 40.5MHz, 49.5MHz clock from a 48MHz, 24MHz, 12MHz and 27MHz master clock input frequency. The output can be enabled or disabled with pin and the frequency can be changed via three-line serial interface. The high performance PLL locks to the master clock input, generating a low jitter, highly accurate clock output without an external crystal.
