GENERAL DESCRIPTION
The High-Speed Serial Logic Translator provides a point solution
that addresses the various interface logic requirements of Optical
Transceiver Modules. The product offers a compact translation
between LVDS and PECL high speed serial data lines. This provides
the end users a simple way to mix or match Optical Transceiver ICs
from various vendors to maximize desired performance and reduces
the need to redesign interfaces to accommodate new Optical
Transceiver ICs.
The High-Speed Serial Logic Translator comes in two translation
choices to allow mixing LVDS and PECL input/outputs. The product
is offered in a small, convenient, 8-pin package.
Figure 1 shows the High-Speed Serial Logic Translator Device in a
typical high speed optical module application. Figure 2 shows the
circuit block diagrams.
