DS92LV0411SQE/NOPB Interface - Serializers, Deserializers

DS92LV0411SQE/NOPB is a serializer/deserializer (SerDes) from Texas Instruments’ family of SerDes devices. This device is a high-speed, dual differential line LVDS serializer/deserializer that is ideally suited for applications operating over electrical backplanes and/or twisted pairs. The DS92LV0411SQE/NOPB supports data rate up to 1.6 Gbps and it provides excellent data integrity, low power consumption and a wide operating temperature range.

Application Field

The DS92LV0411SQE/NOPB supports a wide range of applications, such as backplane communications, digital video, and high-speed networking and storage systems. This device is often used in applications where high data rate and low-power consumption are critical, such as in the telecom, datacom, and storage markets. This device performs the serialization and deserialization of the data. It transmits serial data on a single lane that is up to 8 bits deep.

The DS92LV0411SQE/NOPB is used in computer systems, including high-end servers, computer blades, and other embedded designs, for applications such as computing clusters, streaming video, and communication interface card (CIC) applications, including: 10 Gigabit Ethernet (10GbE) and Fiber Channel. This device is well suited for applications that require high-speed I/O, low-power consumption, and single-lane core logic.

Working Principle

The DS92LV0411SQE/NOPB device is designed to provide an efficient way to transmit and receive data over differential serial interfaces. The device uses a differential signaling mechanism, which allows for higher data rates and less interference than single-ended transceivers. The DS92LV0411SQE/NOPB device serializes and deserializes the data to be transmitted and received, respectively. The device consists of an LVDS transmitter and receiver, a data mux, an 8b/10b encoder, a clock and data recovery (CDR) circuit, and a PLL to generate clock signals for the serialized data.

The LVDS transmitter takes 8-bit parallel data (D0-D7) as input, multiplexes and serializes the data using an 8b/10b protocol, and transmits the data on a LVDS transmit pair (TX1P, TX1N). The LVDS receiver is responsible for serial-to-parallel conversion of the data (RX1P, RX1N) and presents it back to the logic as 8-bits of parallel data (RXD0 -RXD7). The CDR circuit samples and recovers the data bits from the serial data stream without the need for a separate clock signal. The PLL is used to provide a reference clock for both the transmitter and receiver. The clock signal can also be looped back from the receiver to the transmitter to provide clock synchronization.

The DS92LV0411SQE/NOPB device is used in a variety of applications that require high-speed data transmission over electrical backplanes, twisted pairs, and/or other transmission media. The device provides a cost-effective solution for meeting the demands of high speed, low-power, and reliable data transmission over extended distances.
