Other Parts Discussed in Thread: LMK04828, ADS54J20, TSW14J56EVM
According to user guide description i setup the ADS54J20EVM,there are some questions trouble me:
1,When the ADS54J20EVM power-up,the current is 760mA usually,but sometimes is 960mA,it is normal?
2,The user guide description after config board the current is 1.35A,but when i load the LMK04828 config file the current is 1A,after loading the ads54j20 config file the current is down to 700mA,but the PLL2 is locked
As the above problem how can i confirm the ADC is ok?
Another question user guide does not mention the ref clk of LMK04828,how do i choose the ref clk?the external clk or on-board clk?and the vaule?
