CY7B9945V-5AXCT Overview
As a clock IC, it uses the Tape & Reel (TR) package. In the 52-LQFP package, there is an embedded clock generator. 52 terminations can be found in frequency synthesizer. A voltage of 3.3V should be applied to this electronic frequency generator. As the Clock PLL's input, LVPECL, LVTTL is designed to be used in order to generate the clock signal. Using 1 circuits, the electronic part's full performance can be accessed. RF synthesizers based on this clock provide frequencies up to 200MHz maximum. PLL clock is mounted in the way of Surface Mount. The maximum voltage this clock PLL can handle is 3.63V. A maximum voltage of 2.97V should be used for this frequency generator for safety reasons. This clock PLL works with a supply voltage of 2.97V~3.63V. Based on the test statistics, an ambient temperature of 0°C~70°C should be set. LVTTL is designed for clock generator's output. A Clock Buffer, Fanout Distribution is a classification for the electronic part in question. Microprocessor-specific clock PLL with 52 bits. The related electronic parts of part number CY7B9945 are listed below. There are 52 pins on the frequency generator that are available for use. Time clock generator can handle a voltage of 3.3V as the supply voltage. A member of the RoboClock? series, this electronic component is made of plastic. This clock generator offers low timing skew at 0.8 ns Max. If you search for the 7B family of parts, you will be able to find similar electrical parts.
