High-Frequency Fiber Communications
SPICE I/O macromodels aid in the understanding of possible signal reflections and impedance matching issues in electronic systems. Most of Maxim's high-frequency/fiber communication ICs utilize input and output (I/O) circuits with current-mode logic (CML), positive emitter-coupled logic (PECL), and low-voltage differential signal (LVDS) formats to transfer data into and out of an IC. These models are based on simplified circuit expressions that may include replacement of active circuit elements with ideal controlled voltage and current sources. As such, simulation with macromodels should be treated as 'typical' performance and not relied upon as final proof of design. In regards to Maxim's equalizer products, these models do not provide the equalization network(s) used by equalizers, and are therefore not suitable for evaluating equalization performance.
The output format is provided as ASCII text netlists suitable for generic SPICE. This format is compatible with most versions of SPICE, such as PSPICE and HSPICE. Important information is found in HFAN-06.1: Input/Output Models for Maxim Fiber Components.
