Texas Instruments has introduced the industry’s first pair of 10 Gbps serial link aggregator ICs.
The TLK10081 1- to 8-channel and TLK10022 dual-channel ICs allow system designers to reduce the number of gigabit serial links required for communications, video, imaging and other end equipment. They aggregate and de-aggregate point-to-point serial data streams for transmission over backplanes, copper cables and optical links.
With these ICs, designers can avoid the costly and time consuming development of custom aggregator IP for high-performance FPGAs or ASICs. Both devices occupy a claimed 70% smaller footprint than FPGAs and use only two power rails, compared to the five or six rails needed with FPGAs.
The aggregators directly connect serial links from data converters and processors without having to re-format the data for transmission in applications like wireless infrastructure, switches, routers, video surveillance, machine vision, high-speed imaging and optical transport systems.
The TLK10081 can aggregate up to eight lanes of full-duplex, 1,25 Gbps data traffic onto a single 10 Gbps link for transmission over short-distance backplanes or copper cables up to 10 metres, or long-distance optical links. The TLK10022 supports 4:1, 3:1 and 2:1 bidirectional serial link configurations. Each device supports many different data types without requiring special data encoding.
Intelligent serial link switching enables programmable channel lane switching of serial links in different configurations without using external multiplexing. This feature reduces system implementation time while achieving fault tolerance goals. Advanced decision feedback equalisation (DFE) and feed forward equalisation (FFE) extends transmission distances over copper media and optical links.
