Why do we need SerDes?
The primary utilization of SerDes is to facilitate data transmission over a single-line or a differential pair to mitigate the number of input pins, output pins, and interconnects. In summary, we utilize SerDes for the conversion of incoming parallel data into serial data.
What is high-speed SerDes?
A SerDes (Serializer/Deserializer) is an integrated circuit or device in use in high-speed communications that converts between serial data and parallel interfaces in either direction.
What does SerDes stand for?
Serializer/Deserializer
A Serializer/Deserializer (SerDes) is a pair of functional blocks commonly used in high speed communications to compensate for limited input/output. These blocks convert data between serial data and parallel interfaces in each direction.
What is a SerDes channel?
What is SerDes Design? A serializer/deserializer (SerDes) is used to convert incoming parallel data into serial data. This data is sent over a physical channel (such as copper twisted pair, fiber, or a backplane), where it is received as serial data. The receiver then converts this data back to parallel data.
Why is LVDS used?
In addition, LVDS is the physical layer signaling in SCSI standards (Ultra-2 SCSI and later) to allow higher data rates and longer cable lengths. Serial ATA (SATA), RapidIO, and SpaceWire use LVDS to allow high speed data transfer.
What LVDS means?
Low Voltage Differential Signaling
(Low Voltage Differential Signaling) A balanced digital transmission method that is noted for its high-quality signal (low noise). LVDS is used in myriad applications, including LCD monitors, network and peripheral devices, A/V equipment and automotive systems.
What are SerDes in Kafka?
Every Kafka Streams application must provide SerDes (Serializer/Deserializer) for the data types of record keys and record values (e.g. java. lang. String ) to materialize the data when necessary. Operations that require such SerDes information include: stream() , table() , to() , through() , groupByKey() , groupBy() .
How does schema registry work?
Serializer validates data records against the schema: When the application producing data has registered its schema, the Schema Registry serializer validates the record being produced by the application is structured with the fields and data types matching a registered schema.
What is Kafka serialization?
Serialization is the process of converting an object into a stream of bytes that are used for transmission. Kafka stores and transmits these bytes of arrays in its queue. Deserialization, as the name suggests, does the opposite of serialization, in which we convert bytes of arrays into the desired data type.
What is serdes Java?
public class Serdes extends java.lang.Object. Factory for creating serializers / deserializers.
Is schema registry required?
No, Confluent Schema Registry is not required to produce/consume Apache AVRO records in the key or value of a Kafka record. Apache AVRO is a self-contained data container format, where a payload is always accompanied by its schema.
How to speed up Xilinx SerDes?
To push the speed or avoid using global clocking, some extra work might be required. But, with fewer pins, more speed, and all the other benefits, an integrated SERDES is a better solution. We will use the MGT links again and encourage Xilinx to give us both faster and slower SERDES in the future.
What is Xilinx doing in serial technology?
These architectures include networking, telecommunications, and enterprise storage markets served by Xilinx Platform FPGAs with integrated serial I/O transceivers—the ultimate connectivity platform. In addition to this book, Xilinx remains an active participant in key industry organizations help- ing to drive serial technology stan dards.
What is a SerDes implementation?
A SerDes implementation includes parallel-to-serial (serial-to-parallel) data conversion, impedance matching circuitry, and clock data recovery functionality. The primary role of SerDes is to minimize the number of I/O interconnects.
Why world-class Xilinx support?
World-Class Xilinx Support Xilinx backs up their state of the art silicon with quality supporting materials. This includes a wide range of Intellectual Property (IP) cores and reference designs, analog modules and Signal Integrity (SI) design kits, and quality behavior models for digital simulations.
