What is a SerDes interface?
What is a SerDes interface?
The term “SerDes” generically refers to interfaces used in various technologies and applications. The primary use of a SerDes is to provide data transmission over a single line or a differential pair in order to minimize the number of I/O pins and interconnects.
How does a high speed SerDes work?
In essence, a SerDes is a serial transceiver which converts parallel data into a serial data stream on the transmitter side and converts the serial data back to parallel on the receiver side. The timing skew problem encountered in a parallel bus is solved by embedding the clock signal into the data stream.
What is the purpose of SerDes?
The Purpose of SerDes These functional blocks convert data between serial data and parallel interfaces in either direction. 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.
How fast is SerDes?
100 Gbps
The major driving force behind the increasing need for designs that include a SerDes stems from large data centers, where currently, they have throughputs upwards of 100 Gbps. Even with their impressive speeds, there is still urgings to up their performances to 400 Gbps.
What is a SerDes chip?
A SerDes or serializer/deserializer is an integrated circuit (IC or chip) transceiver that converts parallel data to serial data and vice-versa. SerDes chips are used in Gigabit Ethernet systems, wireless network routers, fiber optic communications systems, and storage applications.
Is SerDes analog or digital?
Typically, the SerDes are analog based designs, employing phase-locked loops (PLLs) or delay locked loops (DLLs) (Figure 1 ). The challenge now becomes implementing a large number of PLL/DLL blocks for a multi-gigabit interface that is in very close proximity to high-speed digital circuit blocks.
What is 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. String ) to materialize the data when necessary. Operations that require such SerDes information include: stream() , table() , to() , through() , groupByKey() , groupBy() .
Why do we use 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. The data that we receive is serial data via our physical channels, and the receiver converts this data back into parallel data.
What is Serdes FPGA?
A SerDes is an integrated circuit or device used in high-speed communications that converts between serial data and parallel interfaces, in either direction.
What is serdes Java?
Serdes is a Scala object that contains the implicit conversions with serializers and deserializers for known Scala and Java types and fromFn to create a new Serde[T] (from T or (String, T) ). You should also use Serdes when defining StreamsConfig. …
