The DS90CR285MTD/NOPB is an interface device which functions as an advanced, low-power, and full-duplexed serializer/deserializer designed for slim, long distance applications. It is designed to convert the low-voltage differential signals (LVDS) transmitted over twisted pair or shielded differential cables into highly-reliable clock and data signals. Utilizing this interface, manufacturers are able to reduce the board-level count and provide longer cable lengths while increasing the bandwidth, while also meeting the needs of specific application requirements.

The first application field and working principle of the DS90CR285MTD/NOPB is to transmit high-affinity and high-bandwidth data streams over twisted pair copper cables, for example between multiple backplanes and chipsets in general-purpose computing systems. Its dual-channel serializer/deserializer uses an LVDS-based data link to achieve data rates of up to 8.5 Gb/s at cable lengths of up to 20 meters. Through its Slew-Rate-Controlled Driver, the DS90CR285MTD/NOPB is capable of providing stable high performance over long distances and in electromagnetic interference-prone environments. The device also features a differential input designed for high-speed data (MDC) and one for low-speed data (LDC). Lastly, a spread spectrum and low-power mode is available on both channels for increased compliance to harmonic and jitter requirements.

Furthermore, the DS90CR285MTD/NOPB is also used in applications that require the transmission of low-speed clocks, such as driving a low-speed ADC, and in applications that require communication along serial cable links, such as Ethernet and HDMI. In these applications, the device converts differential speed clocks and signals into the appropriate form and transmits them over LAN connections. The device also provides an auto-directional feature, allowing it to automatically switch between full-duplex transmission and single-ended reception.

Finally, the DS90CR285MTD/NOPB is used to provide high-resolution, low-jitter clocks. These applications require ultra-low-power devices, such as digital video boards, where the device acts as a clock generator and synthesizer. When used with an external architecture, the device is able to generate frequency modulated clocks to tenth-of-a-hertz without jitter while consuming less than 60 µW of power.

In summary, the DS90CR285MTD/NOPB is an advanced, low-power, and full-duplexed serializer/deserializer designed for slim, long distance applications. It is used in applications such as general-purpose computing systems, driving a low-speed ADC, Ethernet, HDMI, and providing high-resolution, low-jitter clocks. This interface device converts the low-voltage differential signals (LVDS) transmitted over twisted pair or shielded differential cables into highly-reliable clock and data signals, and is capable of providing stable high performance over long distances andin electromagnetic interference-prone environments.
