CY7B9945V-2AXI OverviewClock ICs are packaged using the Tray method. In the 52-LQFP package, there is an embedded clock generator. A maximum temperature of 260 can be sustained by this clock generator ic during reflowing. There are a total of 52 terminations in this file. A voltage of 3.3V should be applied to this electronic frequency generator. In this case, LVPECL, LVTTL is designed to be the input of the clock generator. To access the electronic component's full performance, 1 circuits are implemented. The frequency generator has a maximum frequency of 200MHz. Thanks to the Surface Mount, this electric component can easily be installed on a panel. There is a maximum voltage of 3.63V for this clock generator. Keeping the supply voltage for this frequency synthesizer above 2.97V is recommended for safety reasons. There are 2.97V~3.63V available for use with this clock PLL. Test statistics suggest setting the ambient temperature at -40°C~85°C, which is -40°C~85°C. There are several logic levels in LVTTL logic that can be used with this clock generator. It is possible to classify this electronic component as a Clock Buffer, Fanout Distribution. An IC that generates clocks specifically for microprocessors, this clock PLL is 52-bits in si52e. The related electrical components for the base part number CY7B9945 can be found below. A 52 pin is available on the clock PLL. Clock PLL is capable of handling a voltage of 3.3V. It is part of the RoboClock™ series of electronic components. The output frequency is magnified as high as possible with 11 signal outputs. The timing skew of this frequency synthesizer is low at 0.5 nsmax. 7B-family clock generators are similar.
