details
m) AFERST
AFE reset signal.
Output “Low” signal during Reset ( NRESET signal is “Low” )
n) VDD3
+3.3V power pin
Supply +3.3V from an external source.
o) VDDREG
Internal regulator (+1.8V output) power pin
Supply +3.3V.
p) VREGOUT1, REGOUT2
Internal regulator voltage (+1.8V) output pins
Have a capacitor rated at 4.7F or higher inserted between these pins and VSS to
stabilize the regulator.
Wire this pin to VDD2.
q) VDD2
+1.8V power input pin. (Power supplied to internal logic operation from +1.8V)
Wire VDD2 to REGOUT and have a capacitor inserted between VDD2 and VSS.
r) VSS
GND pin.
There is no distinction between +3.3V power and +1.8V power VSSs.
s) AVDD
PLL block power pin
Supply +3.3V. There is no need to distinguish AVDD from VDD3 and VDDREG.
