CY7B9945V-2AXC Overview
This clock IC is packaged using the Tray method. There is a clock generator embedded in the 52-LQFP package. The peak reflow temperature (Cel) amounts to 260 to be essentially indestructible. 52 terminations can be found in frequency synthesizer. Basically, a voltage of 3.3V should be applied to this electronic frequency generator. There is a Clock PLL called LVPECL, LVTTL which is designed to be the input to this clock generator. A total of 1 circuits are implemented to access the full performance of the electrical part. The frequency generator has a maximum frequency of 200MHz. Because of the Surface Mount, clock PLL can be easily mounted on the panel. The maximal supply voltage (Vsup) reaches 3.63V. This frequency synthesizer requires a supply voltage above 2.97V to be safe. Clock generators should operate with the voltage supply of 2.97V~3.63V. Using the test statistics, it is estimated that the ambient temperature should be set to 0°C~70°C. I would like to present to you a frequency synthesizer that is compatible with LVTTL logic levels. It has been classified as a Clock Buffer, Fanout Distribution electronic part, which means that it is a semiconductor. Microprocessor-specific clock PLL with 52 bits. According to the base part number CY7B9945, its related parts can be found. There are 52 pins that are available on the frequency generator. In terms of the supply voltage, PLL clock can handle 3.3V volts. A Clock Drivers clock generator is essentially what this device is. It is part of the RoboClock? series of electronic components. Clock PLL has 11 signal outputs to maximi11e output frequency. As a result of this digital clock generator, there is a low timing skew at 0.5 ns max. This clock generator belongs to the family of 7B.
