RIN, RIN
Reference frequency inputs. These are differential signal
pairs and may be driven differentially or single-ended.
FIN, FIN
Feedback frequency inputs. These are a differential signal
pair and may be driven differentially or single-ended.
HFIN, HFIN
High frequency feedback inputs. These are a differential
signal pair. Differential drive is recommended.
F1, F2
These pins are connection points for the loop filter, which is to
be provided off-chip. F1 is the high impedance side, F2 is the
reference side. The loop filter should be a first order, low pass
with a DC block. The difference voltage on these pins will be
a dc level, which is controlled by the loop feedback and
determined by the required VCO frequency.
FOUT, FOUT
Frequency outputs for the loops. These are differential, positive
referenced, emitter-follower signals and must be terminated
off chip. Termination in 50 ohms is recommended.
HFOUT, HFOUT
High frequency output. These are a differential signal pair.
Termination in 50 ohms is recommended.
S1, S2, S3, S4, S5
These are the frequency select inputs, and are used to
configure the PLL. They are compatible with standard TTL
signal levels. See the Frequency Selection Table for details
of the logic.
VCC
This is the positive supply for the chip. It should be decoupled
and should present a very low impedance in order to assure
low-jitter operation.
VCCO
This is the positive supply for the output buffer. It is constrained
to be equal to or less than the value of VCC. It should be
decoupled and should present a very low impedance for low-
jitter.
VEE
This pin is the negative supply for the chip and is normally
connected to ground (0V).
