CY7B9945V-2AXI Overview
Clock ICs are packaged using the Tray method. As part of the 52-LQFP package, this clock generator is embedded. Frequency generator is capable of operating at a maximum temperature of 260 when reflowing. 52 terminations can be found in frequency synthesizer. A voltage of 3.3V should be applied to this electronic frequency generator. In this clock generator, LVPECL, LVTTL is used as the input to the clock. A total of 1 circuits are implemented to access the full performance of the electrical part. Using this clock-based frequency synthesizer, you can achieve a maximum frequency of 200MHz. With the Surface Mount, it is easy to install this electric component on the panel. 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. There are 2.97V~3.63V different supply voltages that can be provided for this RF synthesizer. By calculating the test statistics, -40°C~85°C is the appropriate ambient temperature. A frequency synthesizer which is compatible with the LVTTL logic levels is presented here. This electronic component can be classified as a Clock Buffer, Fanout Distribution. In particular, this clock PLL is designed to be used with microprocessors. According to the base part number CY7B9945, its related parts can be found. Clock generator is designed with 52 pins. There is a maximum supply voltage of 3.3V that this analog clock generator can handle. In general, this clock PLL is considered a Clock Drivers device. There are a number of electronic parts in the RoboClock? series, including this one. The output frequency can be amplified as high as possible with its 11 signal outputs. As a result of this digital clock generator, there is a low timing skew at 0.5 ns max. By searching for the 7B family, it is possible to find similar electrical components.
