The MAX4951CTP+T is a driver/receiver signal buffer from Maxim Integrated. It provides a high-speed signal retiming, repeating, splitting and fan-out functions, ideal for PCI Express and other system architectures that require ultra-low power performance. This device has an impressive input-to-output delay of 0.5ns, making it one of the fastest driver/receiver combo packs available. This makes it ideal for high-speed computing and networking applications, especially those that require low latency and high throughput.

Application Fields

Maxim Integrated’s MAX4951CTP+T is designed to provide ultra-low power signal buffering and signal splitting. Application fields for the MAX4951CTP+T include:

• Data transmission systems such as Gigabit Ethernet, USB 3.0/3.1 and 5G cellular wireless
• Storage systems such as SAS/SATA and PCIe
• High-speed embedded applications that require reliable signal buffering
• High-frequency Video components, such as digital cameras and digital video broadcasting

Working Principle

The MAX4951CTP+T works by using two low-skew differential receivers to receive two CMOS input signals. The first signal is transmitted through a differential signal buffer, while the second input signal is sent through a repeater driver and a signal fan-out circuit. The signal buffer allows one-to-one retiming of a high-speed clock signal, while the repeater driver can be used to provide a low-skew replication of the input signal for multiple destinations. The repeated signal is sent to the second output port through a signal splitter and a signal fan-out circuit. The repeated signals have an identical output timing and latency to the original input signal.

The MAX4951CTP+T also provides a programmable output voltage selection up to 6V, which is ideal for providing the correct voltage level in 3.3V and 5V systems. The device is highly configurable, with four configurable input resistors, two configurable bi-directional control pins, configurable output driver bias current and output receiver disable capabilities. All parameters can be controlled by two integrated, programmable registers and a two-wire serial interface.

In summary, the MAX4951CTP+T is a convenient and low-cost solution for buffering, retiming, and splitting high-frequency signals. It offers ultra-low power performance, high-speed operation, and a highly configurable interface. This makes it ideal for use in systems which require the most efficient and reliable signal transfer.
