CY7B9940V-5AXC OverviewClock ICs are packaged using the Tray method. In the 44-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 44 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 0°C~70°C, which is 0°C~70°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 Fanout Buffer (Distribution), Zero Delay Buffer. An IC that generates clocks specifically for microprocessors, this clock PLL is 44-bits in si44e. The related electrical components for the base part number CY7B9940 can be found below. A 44 pin is available on the clock PLL. Clock PLL is capable of handling a voltage of 3.3V. With CONFIGURABLE AS SINGLE ENDED TTL ALSO, this clock generator produces better clock signals. It is part of the RoboClockII™ Junior series of electronic components. The output frequency is magnified as high as possible with 10 signal outputs. The timing skew of this frequency synthesizer is low at 0.65 nsmax. 7B-family clock generators are similar.
