AK8151A 1.8V/3.3V Single-PLL Clock Generator AK8151A Features Description The AK8151A is a single-PLL clock generator IC with two outputs. The high performance PLL locks to the master clock input, generating a low jitter, highly accurate clock output without an external crystal. Input Frequency: 27 MHz (1.8V or 3.3V) PLL Output Frequency: Selectable by SEL pin setting 60 MHz or 72 MHz (1.8V or 3.3V) Low Jitter Performance: Period (1): 25 ps typ. Low Current Consumption: The integrated PLL generates 60MHz or 72MHz with 27 MHz input clock. The output frequency is selectable by SEL pin. The AK8151A has two kinds of voltage supply pins. One is for the core and the other is for each of the two output buffers. The core requires 1.8V supply and the output buffers require 1.7V - 1.9V or 2.7V 3.6V supply. Not only the output but also the input accepts 1.8V or 3.3V input clock from Crystal Oscillator. VDDO1 = 3.3V, VDDO2=1.8V, No load 11 mW Typ. (CLKOUT=60MHz) 13 mW Typ.

These are stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Conditions” is not implied. Exposure to absolute-maximum-rating conditions for extended periods may affect device reliability. Electrical parameters are guaranteed only over the recommended operating temperature range. ESD Sensitive Device This device is manufactured on a CMOS process, therefore, generically susceptible to damage by excessive static voltage. Failure to observe proper handling and installation procedures can cause damage. AKM recommends that this device is handled with appropriate precautions.
