The DS90LV049HMT/NOPB device is a product of Texas Instruments, and is an integrated circuit which is typically classified under the Interface category. It is used for various purposes and applications, and it is featured as a driver, receiver or a transceiver type device. The device is dual driver type with an integrated differential pair low-voltage differential signaling (LVDS) driver, hence the long name; it is a high-speed device which is designed to reduce EMI and system power consumption. This article elucidates the application field and working principle of the DS90LV049HMT/NOPB.

In terms of applications, the DS90LV049HMT/NOPB device is primarily used for communication interfaces. As an LVDS driver device, it is used for high-speed communication such as between computers, peripherals or digital displays such as televisions and monitors. It is also used to improve transmission efficiency at lower power and distances. Other applications include as a motor controller, for industrial automation applications, for medical implants and wireless applications. The device is used in many consumer electronics, netbooks and other thin electronic products.

The working principle of the device is relatively simple. It features two high-speed differential HSTL LVDS drivers, which convert LVTTL/LVCMOS signals to low-voltage differential signals. These two differential HSTL LVDS drivers enable complementary signals that go high and low, respectively. They use a differential signaling technique wherein two signals are sent simultaneously in opposite directions across the same transmission line. This method allows more reliable and noise-resilient data transfer as any noise that is generated is cancelled out. The inputs are TTL/CMOS compatible, and the outputs feature robust power-on reset logic that permits power-up and power-down sequencing for hot plugging LVDS applications.

The DS90LV049HMT/NOPB device also has a patented adaptive equalization circuit which compensates for capacitive loads up to 1000 pF(picofarad). The device also utilizes a separate supply for each channel that enables the use of 3.3V for non-critical functions and 1.8V for the critical LVDS circuitry, which improves power consumption. These features and characteristics make the DS90LV049HMT/NOPB device an ideal solution for various communication needs.

To conclude, the DS90LV049HMT/NOPB device is a versatile, low-power, low-voltage differential signaling (LVDS) device which is used in many consumer electronics, netbooks and other thin electronic products. The device features two high-speed differential HSTL LVDS drivers, and it is used for high-speed communication such as between computers, peripherals or digital displays such as televisions and monitors. The device has a patented adaptive equalization circuit and utilizes a separate supply for each channel, thereby improving power consumption. It is an ideal solution for communication needs, and is increasingly becoming more popular in the consumer electronics industry.
