Application Field

The 72V2113L10PF8 FIFO is a product from TI, a globally well-recognized semiconductor maker. It is generally applied in communication and networking, computer, control and instrumentation, data communications and multimedia, etc. At its core, the device is used to buffer data between two devices that operate at different speeds, or otherwise have a rate mismatch. It is typically used when the data is transported through an interface that has the potential to become saturated and thus, the FIFO will allow us to store data during the unfilled time periods of the data stream, thereby allowing us to ensure a steady flow.

Working Principle

The FIFO principle works as follows. Data can be written to the FIFO from one device, typically the one at the lower transfer rate or frequency. This data accumulates in the FIFO until a certain amount of the data has been stored. Subsequently, a menu of write and read pointers is used so that the device at the higher data rate can read the data from the FIFO. The FIFO uses two registers to keep track of the data in the FIFO. The first register is the “depth” register, also called the “fill count” register. The register stores the number of words that have been written in the FIFO. The second register is the “width” register, also called the “read pointer”. The width register stores the number of words that have been read out of the FIFO. When the fill count register is less than the width register, it indicates that the FIFO is empty; when the the fill count register is equal to the width register, it indicates that the FIFO is full; when the fill count is greater than the width register, it indicates that there is data in the FIFO.

Conclusion

The 72V2113L10PF8 FIFO is an ideal device for bridging data rate mismatches between two devices. The data can be written in to the device from one end, and can be read from the other end using the two registers. The FIFO can be used in various application fields to ensure continuous data flow without losses.
