LMH1981评估板可用于评估LMH1981多格式同步分离器,也可以用于设计印刷电路板布局的参考。The LMH1981 evaluation board can be used to evaluate the LMH1981 multi-format sync separator and as a reference for designing the PCB layout. For more information on PCB layout considerations, see the LMH1981 Multi-Format Video Sync Separator Data Sheet (SNLS214).The board should be powered with a clean supply voltage of 3.3 V to 5.0 V using the banana jacks VCC (J2) and GND (J3). The supply should be well-regulated within ±5% variation of the voltage range and should not be shared directly with other digital circuitry.
