AK8150B

ASAHI KASEI EMD CORPORATION 1.8V/3.0V Single-PLL Clock Generator AK8150B Features Description The AK8150B 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. The integrated PLL generates 12MHz with 36 MHz input clock. The device has another output, REF which is to be ICLK or ICLK divided by two. The AK8150B 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 3.3V supply. Not only the output but also the input accepts 1.8V or 3.0V input clock from Crystal Oscillator. Input Frequency: 36 MHz (1.8V or 3.0V) PLL Output Frequency: 12 MHz (1.8V or 3.0V) REF Output Frequency: 36 MHz or 18 MHz (1.8V or 3.0V) Low Jitter Performance: Cycle to Cycle : 200 ps max Period : 120 ps max Low Current Consumption: 7 mW Typ. (REF=18MHz) Output Load: 30 pF Max Supply Voltage: VDD : 1.8V±0.1V VDDO1,2 : 1.8V±0.1V or 3.0V±0.3V Operating Temperature Range: -20 to +85℃ Package: 8-pin USON (2.0mm x 2.0mm) Applications Digital Still Camera Digital Video Camera Block Diagram VDD VDDO1 ICLK INPUT Buffer PLL OUTPUT Buffer1 12M SEL DIV OUTPUT Buffer2 REF GND VDDO2 AK8150B Single PLL with Two Outputs Clock Generator MS0640-E-00 1 Aug-2008 http://www.Datasheet4U.com AK8150B The brand nam...
