[sdiy] AD633 quadrature oscillator

i'm looking to build a VC quadrature sine oscillator with the smallest form
factor possible - i've been eyeballing a few LM13700 based designs, but
rambled upon this design note from the AD633 analog multiplier datasheet
from Analog Devices;
am I right in thinking the multipliers will have through-zero FM
functionality? (they are 4-quadrant multipliers after all...)
also - why is there a diode bridge rather than limiting zeners on that
first feedback loop?
