Guaranteed by design.
V
REF
is normally tied to V
OFFSET
through 50 ohms. If V
REF
is used to provide dc offset to other circuits, it should first be buffered
3.
ENCODE driven by single-ended source; ENCODE bypassed to ground through 0.01 μF capacitor.
4.
ENCODE may also be driven differently in conjunction with ENCODE.
