LVDS转换电路单元的正常工作与否取决于如下条件:U31(DS90C385AMT)①、⑨、(26)、(34)、(44)脚的3.3V的工作电压是否正常;前级电路送到U31-.,脚的HS行同步脉冲是否正常;前级电路送到U3101/的VS场同步脉冲是否正常;前级电路送到U31342脚的DEN(使能信号)同步脉冲是否正常;U31(DS90C385AMT)675脚外接的R204阻值是否正常;前级送来的1024×768/60Hz的TFT格式是否正常。
The normal operation of the LVDS conversion circuit unit depends on the following conditions: whether the operating voltage of 3.3V at the U31 (DS90C385AMT) ①, ⑨, (26), (34) and (44) pins is normal or not; , The HS line synchronization pulse of the foot is normal or not; if the VS field synchronization pulse sent to the U3101 / V3101 is normal or not; whether the DEN (enable signal) synchronization pulse sent to the U31342 pin is normal or not; U31 (DS90C385AMT) 675 Pin external R204 resistance is normal; before sent 1024 × 768 / 60Hz TFT format is normal.
