CDC857-3DGG Overview
It is packaged using the Tube method since it is a clock IC. Embedded in the 48-TFSOP (0.240, 6.10mm Width) package is this Clock PLL. Frequency generator is capable of operating at a maximum temperature of NOT SPECIFIED when reflowing. It contains a total of 48 terminations within RF synthesizer. This clock generator ic should receive a voltage of 2.5V. It is designed that the Clock PLL's input should be LVTTL, SSTL-2. A total of 1 circuits are implemented to access the full performance of the electrical part. Because of the Surface Mount, clock PLL can be easily mounted on the panel. Clock PLL is capable of receiving a maximum of 2.7V as a supply voltage. There should be a voltage supply above 2.3V for this frequency generator in order to ensure its safety. As long as you provide 3V~3.6V supply voltage, it will work. Using the test statistics, we estimate that the ambient temperature should be 0°C~85°C. The RF synthesizer is compatible with SSTL-2 logic levels. An electrical part such as this one can be classified as a PLL Clock Driver component. In this IC, a 48-bit frequency generator is designed specifically for use in microprocessors. This part number is related to its related electronic parts. There are a number of 48 pins that are available on the clock generators. There is a maximum supply voltage of 3.3V that frequency generators can handle. A frequency synthesizer with ALSO REQUIRES 3.3V PLL VOLTAGE features better clock signal output. At 167MHz, frequency synthesizer achieves high efficiency.
