EVALUATION BOARD DESCRIPTION
SY89827L packaged 64-pin EPAD-TQFP with EPAD attached metal component side board improved heat dissipation. high-speed clock inputs, HSTL_CLK LVPECL_CLK brought connectors through matched length differential traces. Three outputs brought through connectors from three sides chip. These HSTL outputs DC-coupled direct connection oscilloscope with standard termination Ground. LVTTL/CMOS control inputs CLK_SEL connected dipswitch board allow different modes conveniently selected.

Setting AC-coupled Evaluation Board following steps describe procedure setting evaluation board. separate voltage sources, VCCI second VCCO. VCCI supply 3.3V VCCO supply 1.8V turn both supplies. Connect terminal negative side power supply. This ground potential. Connect VCCI terminal positive side 3.3V supply. Turn power supply verify that power supply current <140mA. Connect VCCO terminal positive side 1.8V supply. Turn power supply verify that power supply current <40mA. Turn both power supplies. Using differential signal source levels HSTL_CLK inputs 1.0V 1.4V. Using equal length impedance coaxial cables, connect signal source HSTL_CLK inputs evaluation board S6). Using second differential signal source levels LVPECL_CLK inputs 1.5V 2.3V. Turn disable outputs signal source. Using equal length impedance coaxial cables, connect signal source LVPECL_CLK inputs evaluation board S13). Using equal length impedance coaxial cables, connect outputs evaluation board (S24, S25, S38, S39, S63) oscilloscope other measurement device that internal termination. outputs monitored, unused outputs must terminated with ground.
