Why is the RSSI output designed to drive a maximum capacitance of 10pF?
Would it have any damaging or performance consequences to drive it into at higher capacitance?
The RSSI signal is the output from an internal buffer that also drives the signal detection comparator(please see figure 1 of datasheet(Rev 1 6/06)). The 10pF max and 10k ohm minimum resistive load is to prevent the buffer from going unstable/oscillating. A larger capacitance than 10pF can be driven if a 10k ohm isolation resistor is placed between the RSSI output and the capacitive load.
