DESCRIPTION
NAME
NO.
I/O
DESCRIPTION
LOGIC VDD
1
Power supply for the internal logic. This power supply should be separated from VCO VDD to reduce
cross-coupling between supplies.
SELECT
2
I
VCO output frequency select. When SELECT is high, the VCO output frequency is
×1/2 and when
low. The output frequency is
×1.
VCO OUT
3
O
VCO output. When the VCO INHIBIT is high, VCO output is low.
FINA
4
I
Input reference frequency f(REF IN) is applied to FINA.
FINB
5
I
Input for VCO external counter output frequency f(FINB). FINB is nominally provided from the
external counter.
PFD OUT
6
O
PFD output. When the PFD INHIBIT is high, PFD output is in the high-impedance state.
LOGIC GND
7
GND for the internal logic.
TEST
8
Connect to GND.
PFD INHIBIT
9
I
PFD inhibit control. When PFD INHIBIT is high, PFD output is in the high-impedance state.
VCO INHIBIT
10
I
VCO inhibit control. When VCO INHIBIT is high, VCO output is low.
VCO GND
11
GND for VCO.
VCO IN
12
I
VCO control voltage input. Nominally the external loop filter output connects to VCO IN to control
VCO oscillation frequency.
RBIAS
13
I
Bias supply. An external resistor (RBIAS) between VCO VDD and RBIAS supplies bias for adjusting the
oscillation frequency range.
VCO VDD
14
Power supply for VCO. This power supply should be separated from LOGIC VDD to reduce
cross-coupling between supplies.
