Serializers, Deserializers, commonly referred to as SerDes (pronounced "serd-ess”), are interface integrated circuits that convert a digital data stream of a serializer into a stream of parallel bits and vice versa, a deserializer. They are mainly used in high speed data transfer applications, such as in communication network systems, computer buses, etc.DS92LV0421SQE/NOPB is one of the SerDes products from Texas Instruments (TI). It is a high performance and low-power Clock Data Recovery (CDR) device, designed to convert IEEE-1394 physical layer packet formats into 8-bit or 10-bit serial LVDS data streams. It also supports programmable time-stamping and error detection of packets, provides line-rate clock output and support for up to four ports.This device has many use cases. It can be used in a wide range of data applications including consumer electronics, automotive, and industrial applications. Additionally, it can be used in storage and storage area networks, USB and firewire systems, IP core networks, Ethernet, and in telecommunications.In a communication system, the DS92LV0421SQE/NOPB is typically used in an encoding and decoding process. The DS92LV0421SQE/NOPB serializer takes the parallel data bits from the transmitting party and encodes them into a serial data stream. This encoded serial data stream is then sent to the receiving party where the DS92LV0421SQE/NOPB deserializer reconverts it into the parallel format. Both serializer and deserializer functions are fully compliant to the IEEE-1394 Serial Bus Protocol (SBP-2).The DS92LV0421SQE/NOPB has many interesting features, but the most important one is its low-power operation. It requires a supply voltage of 1.8 V and has a typical operating current of 2.75 mA which is much lower than other LVDS products in the market. It also has a built-in power management block which provides power-on reset, low-power control and low-power detection.In addition to its low power operation, the DS92LV0421SQE/NOPB also has an Easy port interface that simplifies board layout and trace routing. It has a total of three ports that can be used for data input/output. The data ports are internally terminated to reduce radiated emissions and noise susceptibility. The DS92LV0421SQE/NOPB also features a selectable output current for improved signal integrity and better signal timing. The device supports data rates up to 900 Mbps and the output current can be set to 40 mA, defining the data rate required by the application. It also has an internal phase-locked loop (PLL) which supports 32 to 64 MHz input frequency range.Overall, the Texas Instruments DS92LV0421SQE/NOPB Serializer/Deserializer Interface IC is an excellent choice for high performance data applications. It has several features that make it well-suited for applications such as consumer electronics, automotive, and industrial applications, allowing for significant power savings. Furthermore, its easy port interface, selectable output current and PLL makes the DS92LV0421SQE/NOPB a great choice for any system that needs to move high-speed data.
