TI introduces the first discrete dual SerDes to support all CPRI and OBSAI data rates

Versatile interface solution supports wireless base station remote radio head applications

(PresseBox) ( Dallas, )
Texas Instruments Incorporated (TI) (NYSE:TXN) today introduced the industry's first 6gigabit per second (Gbps) dual serializerdeserializer IC (SerDes) that enables continuous data rate support from 470 megabits per second (Mbps) up to 6.25 Gbps for wireless applications. The TLK6002 supports speed migration from legacy to new faster speeds in the OBSAI and CPRI standards required for all wireless base station designs. The TLK6002 can be used in a wide variety of wireless infrastructure applications including WiMAX(http://focus.ti.com/analog/docs/blockdiagramdetail.tsp?blockDiagramId=6097&familyId=361&DCMP=hpa_contributed_articles&HQS=Other+OT+wimax-pr), TD-SCDMA(http://focus.ti.com/vf/docs/blockdiagram.tsp?family=vf&blockDiagramId=6099), WCDMA and CDMA2000(http://focus.ti.com/analog/docs/blockdiagramdetail.tsp?blockDiagramId=6098&familyId=361&DCMP=hpa_contributed_articles&HQS=Other+OT+wcdma-pr). For details or to order samples, go to: www.ti.com/tlk6002-pr.

Using either a single 122.88-MHz or 153.6-MHz fixed reference clock frequency, the new SerDes can support Common Public Radio Interface (CPRI(TM)- http://www.cpri.info/) and Open Base Station Architecture Initiative (OBSAI)( http://www.obsai.org/) rates. Also, the TLK6002's 20bit parallel singleended interface connects easily to fieldprogrammable gate arrays (FPGAs). When compared with FPGAs featuring highspeed serial links, a more economical FPGA and TLK6002 combined can provide significant system cost savings

Key features and benefits of the TLK6002:

-Receiver equalization and transceiver preemphasis improves signal integrity by compensating for amplitude losses in cables and for ISI (intersymbol interference), enabling a trace reach of greater than 50 cm.
-Integrated automatic CPRI/OBSAI rate sensing "selftunes" to the system setting, eliminating the need for additional hardware or software.
-Integrated highaccuracy latency measurement (0.6510 ns at 6.144 Gbps) relieves designers' workload by simplifying the system design.
-Supports CPRI/OBSAI data rates: 0.6144, 0.768, 1.2288, 1.536, 2.4576, 3.072, 4.9152 and 6.144 Gbps.
-The TLK6002 complements many TI digital signal processors (DSPs)(http://focus.ti.com/dsp/docs/dsphome.tsp?sectionId=46), data converters(http://focus.ti.com/analog/docs/dataconvertershome.tsp?familyId=82&contentType=4&DCMP=hpa_dc_general&HQS=NotApplicable+OT+dataconverters-pr) and clock(http://www.ti.com/corp/docs/landing/clockdrivers/index.htm?DCMP=hpa_contributed_articles&HQS=Other+OT+clocks-pr) products.

Availability and pricing

The TLK6002 is available in volume now from TI and its authorized distributors in a 324ball BGA package. Suggested resale pricing is $35.00 in 1,000unit quantities.
