Texas Instruments Announces ATM Physical Layer Devices for 155 and 622 MbpsTexas Instruments (TI) announces smaller packaging for its TNETA1500, the most competitively-priced 155 Mbps asynchronous transfer mode (ATM) physical layer (PHY) device currently available on the market.
TI's PHY solutions reduce design costs, which helps drive the
cost of ATM into mainstream networks. TI 155 Mbps PHYs Provide Improved Performance and Lower Cost in a Smaller Package The TNETA1500 is now available in a thin quad flat package (TQFP) in addition to the quad flat package (QFP) that was introduced last year. The TQFP version is 25 percent smaller than the QFP. This not only provides designers a board space savings, but it also enables simplified alignment with optical/electrical (O/E) devices. Both versions of the TNETA1500 prevent generation of runt cells across the receive UTOPIA interface. This eliminates unnecessary processing functions in ATM layer devices, simplifying ATM switch port design. Clock recovery and generation are also integrated on chip. The PHYs are UTOPIA compliant and meet or exceed applicable jitter specifications set by Bellcore.
In addition, the '1500 features the most competitive price for
performance on the market at $36.00 for 1,000 piece quantities
for both the QFP and TQFP packages. 622 Mbps TC Layer Device Offers Revolutionary Price/Performance TI Value Extends Beyond Silicon
The TNETA1500 has been thoroughly tested to assure
functionality and interoperability at one of TI's multiple networking
labs. In addition, TI has recently developed the Networking Technology
Center, a multi-million dollar testing facility that is equipped
with the latest in networking equipment from the major vendors.
This represents TI's commitment to providing robust solutions
to the networking market.
