72V3650L7-5PFI8 is an FIFO (First in, First out) type of logic memory, designed primarily for high speed applications and broadband data transmission. It is a dual bank memory device, made up of two banks of 16,384 taps each and a 48-bit internal address register. The memory device is programmed through a 4-bit interface and is capable of supporting 8-megabit/second data transfer.The device is designed to perform the full range of functions required by the industry-standard FIFO design. As input and output data is shifted, the device keeps track of the current address in the internal register, and stores or retrieves data in the two banks accordingly. This leads to increased throughput and enhanced data-handling performance.The main application for the 72V3650L7-5PFI8 is for high speed data transmission, such as in ATM, optical fiber and Gigabit Ethernet networks, where data rates of up to 8 megabits/sec are required to be managed. The FIFO logic memory device is able to accommodate up to four input and five output ports, exponentially increasing the scope of network applications that it can facilitate.The working principle behind the 72V3650L7-5PFI8 is straightforward and easy to understand. As each new data bit is received, it is written to the next available address in one of the two banks, and then stored in that tap. The internal address register then increments to the next available address, and the process is repeated until all data has been written to the banks.The same process occurs when data is read from the banks. The device uses the internal register to track its current address, and retrieves the data in the corresponding tap. The register then increments and data is retrieved from the next available address, and so on until all desired data is read from the banks.Additionally, the device has a number control signals which can be used to control the flow of data between the two banks, allowing for more efficient switching between the two. This reduces the latency associated with data transfers, further increasing the speed and performance of the device.In conclusion, the 72V3650L7-5PFI8 is a powerful yet simple to use FIFO logic memory device that is ideal for high speed data transmission applications. By tracking the current address in the internal register, the device is able to quickly write and retrieve data to/from the two banks. With enhanced control signals, increased throughput and reduced latency, the device is capable of handling significant data transfer speeds, making it a perfect choice for next-generation data transmission networks.
