Clock Buffers, Drivers, or Line Drivers are integrated circuits designed to distribute high-speed signals with minimal skew, crosstalk, signal alteration, and power consumption. The ICS85454AKLFT is a two-channel Clock Buffers/Drivers designed specifically for memory buffer applications. Its main application field is to buffer clock signals and drive high-speed clock buffers. The logic levels offered by this Clock Buffer are 1.8V, 2.5V, and 3.3V and is suitable for use in DDR memory modules, High-speed IO and FPGAs.

Features

• Low skew inputs
• Up to 256 high speed outputs
• On-chip termination for easy board layout
• Output and power pins-compatible with most other clock buffer products
• System Clock Backup Mode
• Simplified clock distribution network
• Uses 2 channels of ICS85454AKLFT

Working Principle

The working principle of ICS85454AKLFT is that the data input is fed into the buffer, the output signal is converted to a higher voltage level, and then it is distributed to the outputs. This allows for better signal integrity and signal integrity is maintained even in the presence of noise on the input signal line. Also, the device can be used in combination with other clock buffer solutions to create a variety of clock distribution solutions.

The buffer also incorporates on-chip termination and power supply decoupling capability that eliminates the need for external termination resistor and reduces power consumption. The buffer also features a unique System Clock Backup Mode (SCBG), which keeps the clock signal running at a predetermined frequency even in the absence of the master clock. This mode is especially useful when the clock signal is required to run even if the master clock fails.

The ICS85454AKLFT also features up to 256 high speed outputs, making it suitable for applications such as memory buffering and high-speed IO. The buffer is also power and output pins-compatible with most other clock buffer products, making it highly suitable for multi-channel systems.

To sum up, the ICS85454AKLFT is a two-channel Clock Buffer/Driver designed specifically for memory buffer applications and is suitable for use in DDR memory modules, High-speed IO and FPGAs. It offers low skew inputs, on-chip termination, and up to 256 high speed outputs. In addition, it also features the System Clock Backup Mode (SCB) which allows the clock signal to continue running at a predetermined frequency even in the absence of the master clock.
