PTN3342D,118 Application Field and Working Principle

The PTN3342D,118 is an interface dedicated to bidirectional and differential data transmission between a computer and the HDMI connector. It is the driver, receiver and transceiver dedicated to the HDMI interface.

Application field

PTN3342D,118 is widely used in high definition television, set top boxes, audio/video receivers, video game consoles, Blu-ray DVD players, digital media adapters, digital cameras and camcorders.

It is also widely adopted by industrial systems, medical field and digital signage applications, such as portable medical device, military storage devices and High Definition Multi-Media Interface (HDMI) high definition displays.

Working Principle

The high-definition media interface connector of the PTN3342D,118 utilizes differential lines to transfer high-bit-rate digital audio and video signals. To accurately receive and transmit these signals, the PTN3342D,118 requires a pair of complementary differential lines running in parallel which are used to send out and receive signals in a bidirectional fashion.

Two equal and opposite voltages are used on each of the two lines to produce a differential signal. One line carries the signal, while the other line is used for negating the signal, thus producing an opposite effect. The PTN3342D,118 is also designed to protect itself from electromagnetic interference (EMI) by generating a common mode rejection. This rejection ensures that video signals remain clear and without any distortion from noise.

The PTN3342D,118 also has a built-in power management system to reduce power consumption. The power management system controls the voltage used on the lines and can be adjusted manually or with automatic switching. This allows the device to be used in different kinds of applications with different requirements and power levels.

The PTN3342D,118 is a reliable and cost-effective device for the transmission of high-quality video and audio signals across HDMI connectors. It is an essential component for the creating of high-definition video devices that require bidirectional data transfer.
