NBC12439AFAR2G Overview
Clock generator is packaged in the way of Tape & Reel (TR). Clock PLL is embedded in the 32-LQFP package. The peak reflow temperature (Cel) amounts to 260 to be essentially indestructible. 32 terminations can be found in frequency generators. The supply voltage of 3.3V allows for high efficiency. Crystal is designed for clock generator's input. 1 circuits are used to achieve clock PLL's superior flexibility. 800MHz is the maximal value for normal operation. PLL clock is mounted in the way of Surface Mount. Clock generators should operate with the voltage supply of 3.135V~5.25V. The temperature should be set at -40°C~85°C to ensure reliable performance. PECL is designed for clock generator's output. This electronic component can be classified into PLL Clock Generator. Clock PLL is equipped with 32 pin count. According to the base part number, its related parts can be founded. Clock generator is designed with 32 pins. The supply voltage should be maintained at 5V for high efficiency.
