Industry's first discrete serial link aggregators support data rates up to 10 Gb/s

Aggregator ICs reduce cable interconnect costs, power consumption and development time for serial link-based systems

DALLAS, TX - Texas Instruments introduced the industry's first pair of 10-Gb/s 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 many other end equipment. They aggregate and de-aggregate point-to-point serial data streams for transmission over backplanes, copper cables and optical links. With TI aggregator ICs, designers can avoid the costly and time-consuming development of custom aggregator IP for high-performance FPGAs or ASICs. Both devices occupy a 70-percent smaller footprint than FPGAs and use only two power rails, compared to the five or six rails needed with FPGAs.

TI serial link 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-Gb/s data traffic onto a single 10-Gb/s link for transmission over short-distance backplanes or copper cables up to 10 meters, or long-distance optical links.

Key features and benefits of the TLK10081 and TLK10022:

Reduced system design complexity: Unique class of interface IC offers multiple serial link aggregation configurations that deliver 10-Gbps maximum throughput to reduce system design complexity, implementation costs, board space and power consumption. The TLK10022 supports 4:1, 3:1 and 2:1 bidirectional serial link configurations, while the TLK10081 manages 8:1 bidirectional links.

Data agnostic aggregation: 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 innovative feature reduces system implementation time while achieving fault tolerance goals.

Built-in digital equalization: Advanced decision feedback equalization (DFE) and feed forward equalization (FFE) extends transmission distances over copper media and optical links.

The TLK10081 and TLK10022 can be combined with other TI devices to create a signal chain solution: ADS42JB69 dual 16-bit, 250-MSPS analog-to-digital converter (ADC) with JESD204B serial interface, SN65LVCP1414 14.2-Gbps 4-channel equalizer and SN65LVCP114 14.2-Gbps quad mux redriver. These new aggregator devices join TI's growing portfolio of interface products that equalize, switch, re-time and aggregate high-speed serial links.

Tools and support

The TLK10081EVM and TLK10022EVM evaluation modules are available today for a suggested retail price of US$2,999. They are supplied with an EVM user guide and GUI software with user guide, enabling system designers to configure the device for their application.

A video aggregator application note is also available, as well as IBIS-AMI and HSPICE simulation models to verify signal integrity.

Support is available on the High Speed Interface Forum in the TI E2E™ Community, where engineers can search for solutions, get help, share knowledge and solve problems with fellow engineers and TI experts.

Availability, packaging and pricing
The TLK10081 and TLK10022 are available today in 13-mm by 13-mm, 144-ball plastic BGA packages for a suggested retail price of US$25 in 1,000-unit quantities.
