Supply voltage pin for the Pre-Mixer.

An internal regulator helps keep the

device stable against temperature or

VCC variation.

Output from the Pre-Mixer. This pin

is designed as open collector. Due

to the high impedance output, this

pin should be externally equipped

with LC matching circuit to next

stage.
