72V03L15J8 is a high speed synchronous FIFO operating at data rates up to 212 MHz and I/O voltages from 1.8V to 3.3V. It is ideally suited for applications that require the transfer of data between asynchronous domains or among different clock frequencies. The FIFO can operate in stand-alone or cascaded modes and provides flexible controls to configure the FIFO to support various operational and system requirements.

Application Field

72V03L15J8 is mainly used in PC system and server system. In the PC system, 72V03L15J8 is used in high speed multimedia NIC, high speed graphics card, PCI Express, high speed USB, SATA, and other high speed transmission systems. In the server system, 72V03L15J8 is used in integrated high speed communication systems such as SAN, Infiniband, and HyperTransport.

Working Principle

72V03L15J8 uses a synchronous design that consists of two independent first-in first-out (FIFO) data registers and an associated control logic unit. The FIFO stores data sent to it serially on its input pins, and sends data out serially on its output pins. The FIFO can be configured to operate in Push mode or Pull mode. In Push mode, data is loaded only when the "Push_in" signal is asserted and the FIFO is not full. In Pull mode, data is unloaded only when the "Pull_out" signal is asserted and the FIFO is not empty.

The 72V03L15J8 also has an input select feature that allows the user to select between multiple sources for input data. This feature allows data to be routed from multiple sources to one or more destinations. The FIFO has an advanced underflow and overflow protection feature which prevents data from being lost or corrupted due to pipeline clock delays.

The 72V03L15J8 also provides a number of advanced features to ensure data integrity such as parity checking, programmable data framer, and loopback mode. Parity checking is used to detect single bit errors in the data stream while the programmable data framer is used to detect multi-bit errors. The loopback mode allows the user to test the FIFO operation in a loopback configuration.

The 72V03L15J8 also provides an internal synchronization mechanism that allows the FIFO to adapt to different clock rates. This allows data to be transferred between devices operating at differing clock rates without the need for external clock synchronization.

In summary, 72V03L15J8 is a high speed synchronous FIFO operating at data rates up to 212 MHz. It can be configured to meet various requirements and provides features such as parity checking, programmable data framer, loopback mode, and synchronization mechanism to ensure data integrity. 72V03L15J8 is mainly used in PC and server systems and is particularly useful in applications that require the transfer of data between asynchronous domains or among different clock frequencies.
