APPLICATION INFORMATION
Vout Connection output should connected coupling capacitor next stage receiver filter decision circuits), output buffers designed drive coupled load. Vout connected high input impedance decision circuit (>500W), then coupling capacitor required, although caution should exercised since offsets photo detector/TIA combination cause clipping subsequent gain decision circuits. Power Supplies General Layout Considerations ATA30013 operated from positive supply high Below bandwidth sensitivity will degrade, while bandwidth, sensitivity improve. device much less sensitive same changes Vss. surface mount (preferably type capacitors), inductance power supply bypass capacitors (>=56pF) essential good high frequency noise performance. power supply bypass capacitors should mounted connected good inductance ground plane. General Layout Considerations Since gain stages transimpedance amplifier have open loop bandwidth excess GHz, essential maintain good high frequency layout practices. prevent oscillations, inductance ground plane should made available power supply bypassing. Traces that made short should made short, utmost care should taken maintain very capacitance photodiode-TIA interface (Iin), excess capacitance this node will cause degradation bandwidth sensitivity. Sensitivity Bandwidth order guarantee sensitivity bandwidth performance, subjected extensive series tests sort level (100% testing 25oC) verify parametric performance high frequency performance (i.e. adequate amplifier. Acceptably high internal gain stages will ensure amplifier input capacitance, hence, input reference noise current. Transimpedance sensitivity bandwidth then guaranteed design correlation with sort test results.
