72245LB10TF belongs to Logic - FIFOs Memory. It is an integrated circuit for high-speed packet switching. It features 10-bit wide by 5-bit deep synchronous dual-port memory, clocked in both directions. 72245LB10TF is typically used in high speed packet switching, telecommunication, and LAN/WAN network interface.

Application Field

72245LB10TF is ideal for common medium and large-scale packet switching applications. It is capable of buffering high data rate multiplexed streams on the port side while forwarding them to the different destinations on the backplane side. This feature makes it ideal for telecom, network switching applications, as well as point-of-presence in large networks.

The device also features two distinct channels for two-way transactions. This is highly advantageous for network designers as it permits the applications of a single IC on both the front and back planes of the system. It significantly reduces the hardware components to be used, resulting in space and cost savings.

The 72245LB10TF is commonly used in video conferencing, Ethernet switching, and telecommunication systems as it has excellent packet rate performance and improved backplane utilization. The device also provides optimal buffering performance with certain transmit frames which can achieve up to 32KB shift.

Working Principle

72245LB10TF operates using the dual port configuration, where each one points in a particular direction. The port side point towards the ports of the system while the backplane side points towards the backplane of the system. This allows data to be accessed from both sides at the same time.

The device uses a FIFO memory architecture to operate. In a FIFO memory architecture, data are written in a first-in-first-out (FIFO) manner and the order of data retained. In a FIFO, the first data written will be the first data to be removed. The FIFO memory that is used in the 72245LB10TF has a fixed depth of 5 and a width of 10 bits. Data is read from the FIFO in a continuous format and the read process is clocked in both directions.

The device also features two distinct channels, which are referred to as the port side and the backplane side. The port side handles the transfer of data between the ports and the backplane while the backplane side handles the transfer of data between the backplane and the ports. Each side has its own memory block and they can operate independently. The port side is responsible for receiving and sending data while the backplane side is responsible for the buffering of data.

The device is designed using low power CMOS logic and is self-timed for balanced, single-ended and clock/data synchronization signals. The device offers low power dissipation and does not require a positive supply voltage, which makes it ideal for use in telecom and high speed packet switching applications.
