Serdes

About Serdes

SERDES macrocell circuits receive fast serial signals on the order of mbit/s or higher and de-serialize them into slower, parallel signs. They are used in high-speed communications and include a DC-balanced coding scheme such as 8B/10B encoding. SERDES is an abbreviation for serializer/de-serializer. They include serializers that function as serial-to-parallel converters and deserializers or receivers that convert parallel data into serial form. Most SERDES macrocells are low-power, high-performance devices. Using a SERDES chip can reduce the number of necessary wires or pins by transmitting parallel data between two points over a serial stream. Some SERDES circuits can be programmed like any other programmable logic device (PLD).

A SERDES circuit consists of integrated serializers and deserializers that can be used to convert parallel data into serial form, or serial data into parallel form. Typically, a SERDES circuit includes SERDES memory. When data bits are transmitted, a start bit at the beginning and a stop bit at the end are appended so that the receiver can determine where the packet starts and ends. Advanced on-chip diagnostic intelligence helps to test and monitor high-speed serial links for the determination of the bit error rate. As a rule, the speed of a SERDES chip is a function of the device with which it is used. In some cases, the operating speed can exceed 10 Gbps; however, a SERDES circuit is usually used with devices that are capable of handling 3.125 to 3.75 Gbits/s. Other SERDES macrocell circuits may carry additional specifications.
