DSLVDS1047: The current of DSLVDS1047-1048EVM

samba wang

Part Number: DSLVDS1047

The current raised 438mA when we input 20MHz square wave in DSLVDS1047-1048EVM . And now we connected 1047 to 1048 using one twist cable which is 80cm lenth . So anyone can help to explain why the current is so high .

Thanks!

Hi,

Can you check the solder joints of the ICs? Where is the square wave input on the input? J5?
