Moving Forward With the GTL16612A
TI has continued to improve the characteristics and features of the GTL family to provide higher throughput rates at backplane
frequencies up to 80 MHz. These higher frequencies allow designers to transmit increased amounts of data on their board,
achieving high bit rates in their systems. The newest device in the GTL family, the GTL16612A, an improved version of the
GTL16612, is capable of operating at frequencies as high as 80 MHz. The features of this device include output edge control
(OEC) on the rising and the falling edge, and optimization for high-performance distributed-load applications. Simulation
results that provide a comparison between the GTL16622A and the GTL16612A are shown in Figures 12 and 13 at 50 MHz
and 66 MHz, respectively.
