CY7B9940V-2AXC Overview
Tray-method packaging is used for clock ICs. This clock generator is embedded in the 44-LQFP package. In the reflowing process, this clock generator ic is able to maintain a maximum temperature of 260. There are a total of 44 terminations in this file. A voltage of 3.3V should be applied to this electronic frequency generator. A clock generator's input is called LVPECL, LVTTL and it is designed as the input for this clock generator. A total of 1 circuits are implemented to access the full performance of the electrical part. A clock-based RF synthesizer that provides a max frequency of 200MHz is available. Surface Mount-slots make it easy to mount this electronic component on panels. It would take a maximum supply voltage of 3.63V to operate this time clock generator. It is safe to use this frequency synthesizer with a supply voltage above 2.97V. This clock PLL works with a supply voltage of 2.97V~3.63V. Based on test statistics, ambient temperature should be set at 0°C~70°C. As the name suggests, this is a clock generator that is compatible with LVTTL logic levels. A Fanout Buffer (Distribution), Zero Delay Buffer is a classification for the electronic part in question. Microprocessors are specifically designed to use this clock-generating IC, which has a 44-bit output. According to the base part number CY7B9940, its related parts can be found. There is a 44 pin that is available on the frequency synthesizers. There is a maximum supply voltage of 3.3V that electronic frequency generator can handle. In general, this clock PLL is considered a Clock Drivers device. The RF synthesizer features CONFIGURABLE AS SINGLE ENDED TTL ALSO for improved clock signal output. RoboClockII? Junior series electronic parts are included in this product. The output frequency is magnified as high as possible with 10 signal outputs. This clock generator offers low timing skew at 0.65 ns Max. A search for the 7B family will yield similar electronic parts.
