Notes:
1) Normal mode: Connect VSS_EXT (pin 2) to GND (VSS_EXT = 0V) to enable internal negative voltage generator. 2) Bypass mode: Use VSS_EXT (pin 2) to bypass and disable internal negative voltage generator. 3) Due to startup inrush current, a minimum current limit of 600 µA is al owed for normal operation of the DSA. 4) Applies to al pins except pins 18, 22, 23 and 24. P/S (pin 18), A0/D4 (pin 22), A1/D5 (pin 23), and A2/D6 (pin 24) have internal 1.5 MΩ pul -up resistor to internal 1.8V VDD. 5) 100% duty cycle, al bands, 50Ω. 6) ≤ 5% duty cycle, 50Ω. 7) The maximum peak envelope of any OFDM complex waveform signal, such as CP-OFDM, should not exceed the maximum peak RF input power in
Table 1
. The maximum average power of any complex waveform should not exceed the operating maximum RF input power, CW.

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).
