+3.3 V 5% power supply (for logic section of
SONET/SDH framer).
+3.3 V 5% power supply (for analog circuits,
PLLs). This supply should be filtered very care-
fully (max. ripple 5 mVpp) since the quality of this
voltage determines the jitter performance of the
PLLs. Use of a linear regulator is mandatory.
