Positive value indicates current source; negative value indicates current sink. ANT_DET (pin 8) Characteristics ANT_DET (pin 8) is an input and output logic signal. In output mode, it operates as an indicator of the current through ANT_BIAS (pin 2). In input mode, an input needs to be applied which overrides the output from the pin, to force the internal antenna-switch.

(2) When ANT_DET (pin 8) used as a logic output. (3) The ANT_DET (pin 8) output drive is asymmetric. When outputting logic ‘0’, the output looks like a current sink of 300uA. When outputting logic ‘1’, the output looks like a pull up resistor of 50kohm to VCC. The 300uA sink is enough to pull the output logic level to GND, with a 10kΩ resistor to VCC. Logic Output Current Drive Adjustment Settings The Logic Outputs on the SE4150L can be adjusted to compensate for parasitics in application board layout. This can be achieved by adding a resistor between RVI (pin 12) and VDDQ (pin 14) as shown below. The additional interface capacitance of PCB tracking and connectors between the SE4150L output and baseband IC input is included in these figures. These figures are Typical only, and are not guaranteed across temperature and silicon process.
