CY7B9945V-2AXC OverviewTray-method packaging is used for clock ICs. The 52-LQFP package contains this clock generator. This clock generator ic can sustain a maximum temperature of 260 during reflowing. It contains 52 terminations that can be found in frequency synthesizer. This electronic frequency generator requires a voltage of 3.3V. The input of this clock generator is designed to be LVPECL, LVTTL. To access the full performance of the electronic component, 1 circuits are implemented. There is a maximum frequency of 200MHz Max with this clock-based frequency generator. Thanks to the Surface Mount, this electric component can be conveniently installed on the panel. This clock generator would require a maximum supply voltage of 3.63V. For safety reasons, this frequency synthesizer should have a voltage supply above 2.97V. As far as the supply voltage is concerned, clock PLL can be used with 2.97V~3.63V. Based on the test statistics, an ambient temperature of 0°C~70°C should be set. As the name suggests, this is a clock generator that is compatible with LVTTL logic levels. This electronic component is usually classified as a Clock Buffer, Fanout Distribution component. The clock-generating IC is a 52-bit device designed specifically for microprocessors. You can find related electrical components to the base part number CY7B9945. It is possible to connect to the frequency generators via 52 pins. There is a maximum supply voltage of 3.3V that clock generator can handle. The RoboClock™ series includes this electronic part. 11 signal outputs enable clock PLL to magnify output frequency as high as possible. At 0.5 ns Max, this clock generator offers low timing skew. When searching for parts of the 7B family, similar frequency generators will be found.
