The LTC1327CSW#TRPBF is physically small, measuring only 1x1x0.6 mm, making it suitable for applications where size and package minimization is a priority. It is capable of driving up to 0.9V p-p voltage output swing differential.

Application Field

The LTC1327CSW#TRPBF has applications in low-power, differential line-interfacing applications. It offers an extremely cost-effective solution for MDIO transmitters, receivers, and transceivers. It can be used in a wide range of applications including Ethernet, High Speed Interconnects (HIPPI, InfiniBand, 1000BASE-T), and point-to-point communications. It is suitable for implementation in applications where strict power conservation requirements must be met.

Working Principle

The LTC1327CSW#TRPBF is based on the source-synchronous logic family. It functions as both a driver and a receiver, allowing it to act as a transceiver. It contains a low-power differential output driver, low-power differential receiver, and power-saving circuitry that allows the device to automatically adjust its idle state to the operating conditions.

The device is designed to operate from a single 1.8-5.5V supply. Its low-power differential receiver operates with a threshold voltage as low as 0.86V and can be used to sense signals as low as 0.65Vp-p swing differential. The driver is capable of outputting 0.9V p-p swing differential with a minimum peak-to-peak voltage output level of 1V.

The LTC1327CSW#TRPBF provides an integrated complementary ESD a protector, which helps protect the circuit from external electrostatic discharge (ESD) or other over-voltage events. It also provides fault protection for ESD strikes on the driver/receiver nodes. Additionally, the device implements power-saving techniques such as energy-efficient idle state and auto shut-off.

The LTC1327CSW#TRPBF is designed to provide excellent data integrity even in noisy environments. It utilizes advanced noise cancellation and analog equalization techniques to maintain high signal integrity and receiver performance. Additionally, the device supports half-duplex and full-duplex applications, and supports a data rate of up to 1000 Mbps.

The device is characterized for operation over extended temperature ranges of -40°C to 85°C, making it suitable for use in critical or harsh applications. It also has a low profile QFN-14 package that helps in reducing the overall form factor of the system. The very low power consumption of the device makes it ideal for portable, battery-powered applications.
