The device serves no less than an essential role for a wide variety of applications, evolving and increasing the capability and performance of the working technology. This article will explain the application field and working principle of the DS90C402M/NOPB.

Application of the DS90C402M/NOPB

The DS90C402M/NOPB is a low-voltage differential signal (LVDS) receiver of Texas Instruments’ industry-leading catalog of Inter-Integrated Circuit (I2C) products. It enables reliable data transmission over low-voltage, low shielding-modulation, point-to-point links supported via serial LVDS. This technology is ideal for transferring high-quality video and audio signals from a wide range of types of camera sensors to a digital signal processor (DSP) or digital video receiver.

The device is also ideal for general purpose data communications with high speeds of up to 640 Mbps and low power consumption. In addition, it supports multiple data rates with an integrated phase-locked loop (PLL). Such features make this device highly versatile and applicable to a diverse range of industrial and consumer applications. Examples of such applications include:

• Video, audio and imaging products
• Fiber-optic communication systems
• Network communication products
• Multi-processor control systems
• Graphic LCD controllers
• Broadcast video displays
• Servers, storage systems and other computer equipment

Working Principle of the DS90C402M/NOPB

The DS90C402M/NOPB is designed for applications requiring high data rates and low power. This reduced power requirement without compromising on the data rate is achieved through the combination of the LVDS signaling technology and the integrated PLL. The LVDS technology helps to reduce noise and spurious signals, enabling the device to work on low voltage and lowattenuation transmission lines.

LVDs operate by encoding data into small differential voltage changes between two physically adjacent conductors. This approach maximizes the signal-to-noise ratio (SNR) and reduces emitted radiation, which helps to reduce the electromagnetic interference (EMI) the device would otherwise produce. LVDS also improves data dispersal, eliminating common-mode radiation, and allowing for better communications between multiple system points.

The PLL circuitry within the DS90C402M/NOPB is used to generate a fixed-frequency clock on which the receiver/transmitter operations are based. This clock enables the device to achieve higher data rates while remaining robust against timing jitter and environmental noise. Moreover, the PLL helps to overcome the limited range of frequencies available from various low-cost reference oscillators, giving the manufacturers and designers greater design flexibility.

In addition, the DS90C402M/NOPB supports a range of output controls and test capabilities, ensuring that the device operates with minimal disruption and achieves optimal performance. These features enable designers and engineers to meet the latest data communication requirements for a range of consumer and industrial applications.

In conclusion, the DS90C402M/NOPB offers a highly versatile design solution with a wide range of applications. Its combination of low voltage differential signaling and integrated PLL enable reliable data transmission at higher speeds with reduced power consumption. Furthermore, its test capabilities and output controls ensure the device works to its full potential, allowing designers and engineers to meet the most demanding consumer and industrial requirements.
