                                                DS1090U-1+T Overview
As a clock IC, PLLs is packaged using the Tape & Reel (TR) method. Embedded in the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package is this Clock PLL. 8 terminations can be found in frequency synthesizer. For this clock generator ic, a voltage of 3.3V is required. Clock is designed as this clock generator's input. A total of 1 circuits are implemented to access the full performance of the electrical part. This clock-based frequency generator provides a frequency up to 8MHz Max. Because of the Surface Mount, clock PLL can be easily mounted on the panel. As long as there are 3V~5.5V supply voltages provided, clock generator ic should work. By calculating the test statistics, -40°C~85°C is the appropriate ambient temperature. As the name suggests, this is a clock generator that is compatible with CMOS, TTL logic levels. This electronic component can be classified as a Clock Generator. Related electrical parts can be found for the base part number DS1090. The clock PLL has 8 pins that are available.  EconOscillator? series electronic parts are used in this part.
