SY58609/10/11U Evaluation Board configuration board -3.3V. This allows body connectors, which scope GND, appear same potential output drivers. SY58610U DC-Coupled Evaluation Boards DC-coupled operation, boards modified power supplies "split-supply configuration." term split-supply simply means +3.3V supply split into -1.3V, +2.5V supply split into -0.5V power supply configuration. This effectively offsets board +2V. offset this two-power supply configuration then provides correct terminations device setting Ground potential board exactly volts below supply. voltage then -1.3V 3.3V devices -0.5V 2.5V devices device power pins still full 3.3V 2.5V potential between VEE. SY58611U DC-Coupled Evaluation Boards DC-coupled operation accomplished modifying board power supplies into "split-supply configuration". order correctly interface LVDS 50-(to-ground) scope, must VOCM above level. Therefore, 2.5V supply will split into +1.2V -1.3V ensure ensure proper voltage difference. Step-by-step instructions modifying AC-coupled evaluation board DC-coupled operation supplied section "Modifying your AC-coupled Board DCCoupled Operation."
Evaluation Board Description
SY58609U, SY58610U, SY58611U share common evaluation board. individual evaluation boards labeled identify specific device configuration. SY58609U, SY58610U, SY58611U CML, LVPECL, LVDS output evaluation board respectively. default configuration boards ACcoupled configuration. choice between configurations offers flexibility different applications. AC-Coupled Evaluation Board AC-coupled configuration suited most customer applications preferred majority users because ease-of-use. requires only single power supply offers most flexibility when interfacing variety signal sources. DC-bias levels AC-coupling capacitors supplied on-board each input. user only needs supply minimum input voltage swing bias voltage will automatically adjust input correct level power supply voltage varies. DC-Coupled Evaluation Board SY58609U DC-Coupled Evaluation Boards allow outputs used DC-coupled configuration with scope that standard termination, power supplies configured offset voltage evaluation board negative. 2.5V configuration board -2.5V. 3.3V
