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
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.
