DESCRIPTION
39 DCPL
Power (Digital)
1.7V-1.85 V linear voltage regulator output to which a 1 uF decoupling capacitor should be
attached. For test-purposes an external digital supply voltage (1.62-1.98 V) can be applied
here, bypassing the voltage regulator.
NOTE: The voltage regulator is intended for use with the CC8520 chip only. It cannot be
used to provide supply voltage to other devices.
40 DVDD
Power (Digital) Digital power supply for the linear voltage regulator.
1 _{Digital I/O pad with 4 mA source/sink capability, programmable direction and pull-up, pull-down or high-impedance.}
2 _{Digital I/O pad with 20 mA source/sink capability, programmable direction and pull-up, pull-down or high-impedance.}
