SI4123-D-GM Overview
Clock generator is packaged in the way of Tube. Clock PLL is embedded in the 28-VFQFN Exposed Pad package. 28 terminations can be found in frequency generators. The supply voltage of 3V allows for high efficiency. Crystal is designed for clock generator's input. 1 circuits are used to achieve clock PLL's superior flexibility. 1.8GHz is the maximal value for normal operation. PLL clock is mounted in the way of Surface Mount. The supply voltage (Vsup) should be kept above 2.7V for normal operation. Clock generators should operate with the voltage supply of 2.7V~3.6V. The temperature should be set at -40°C~85°C to ensure reliable performance. Clock is designed for clock generator's output. This electronic component can be classified into Frequency Synthesizer. Clock PLL is equipped with 28 pin count. According to the base part number, its related parts can be founded. Clock generator is designed with 28 pins. The supply voltage should be maintained at 3V for high efficiency. IC clock generator consists of 3 elements.
