IDT72P51369L6BBI8

Application Field and Working Principle of IDT72P51369L6BBI8

The IDT72P51369L6BBI8, developed by Integrated Device Technology, Inc. (IDT), is a low latency to 1,6 Gb/s 3.3 Vpoint-to-point differential link transceiver, specifically intended for connecting two 3.3 V devices. The product is designed for high-speed communication systems operating over serial data channels and provides the physical “glue” to electronically connect high performance personal computers, workstations and servers for telecommunications and networking applications.

Features

At a high level, the IDT72P51369L6BBI8 features:

• 80 Ps resolution time stamping
• Supports point-to-point differential links data rates from 0.3 to 1.6 Gb/s
• Validated through 25 m cables, with multiple devices in chain
• Low power consumption (2.5 W typical)

The device also supports 5 V tolerant logic pins and a max pulse width distortion of 0.77 UI on its differential pair output. Packaging for the IDT72P51369L6BBI8 is provided in a 52 pin Total Power 8TM BGA package.

Architecture

The device follows a multilayer protocol for communication, combining Synchronous Optical NETwork (SONET)/Synchronous Digital Hierarchy (SDH) and Large Scale Integration (LSI) technology. This allows the IDT device to ensure power calibration and optimize the operation of the transceiver to efficiently minimize the power consumption while maintaining a reliable link.

Operation

The IDT72P51369L6BBI8 is comprised of three key components: the transmitter, receiver and calibration blocks, as well as the temperature monitor. The transmitter section implements up to 1.6 Gb/s link rate transmission, while the receiver section implements up to 1.6 Gb/s link rate reception. The calibration block is used to encode data signals and adapt the transmitter to the receiver. The temperature monitor monitors the IC’s temperature and initiates thermal protection if needed.

In normal operation, the IDT72P51369L6BBI8 transceiver will be sending/receiving data with the receiver at the same data rates as its transmitter. The calibration block will monitor and adjust the voltage swing of the data signals generated by the transmitter to make sure the data signals reaching the receiver are identical. The temperature monitor monitors the IC temperature and initiates thermal protection if the temperature exceeds the maximum safe operating temperature.

Benefits

The IDT72P51369L6BBI8 transceiver offers advantages such as:

• Low latency (as low as 80 ps) signaling rates
• Ensures power calibration to optimize power consumption
• Detailed temperature monitoring
• Small size and packaging
• Low cost when compared to alternative solutions

The IDT device is suitable for high-speed, 3.3 V applications which require various link rates and support for various protocols. The device also offers flexibility in applications as it allows users to select from models with different port configurations, such as single, dual and quad port.

Conclusion

The IDT72P51369L6BBI8 transceiver is a versatile, 3.3 Vpoint-to-point differentials link transceiver suitable for various applications and protocols. The device offers low latency transmission, enhanced monitoring and calibration capabilities, as well as low power consumption and low cost compared to alternative solutions.
