When RF input power is applied, positive output power spikes are prevented during attenuation state changes by optimized internal timing c... Truth Tables Serial Addressable Register Map Programming Options Parallel/Serial Selection Parallel Mode Interface For direct parallel programming, the LE line should be pulled HIGH. Changing attenuation state control values changes the device state to new attenuation. Direct mode is ideal for manual control of the device (using hardwire, switches, or jumpers).
