Hi,
I'm using LMH6521 on a new board.
I've some difficulties to control the amplifier in Serial mode.
I can correctly write and read the device trough the SPI pins.
Aftern enabloing the ENB or ENA i see something on spectrum analyzer but chaning attenuatoion value nothing changes.
When I write, first bit is always one to apply proper attenuation immediatly.
I have double check scheamtic and footrpint but I did't find any difference from evaluation board.
Any suggestion?
thanks
Davide
