The AZ12010 contains all of the functional elements necessary to implement a Phase-Locked Loop for clock
multiplication at frequencies up to 800 MHz. A fixed 32 times multiplication allows the use of low cost crystals or a
low frequency reference signal. The output can be divided by two for 16 times net multiplication. The VCSO is
differentially or single-ended driven using the chip CML SAW outputs. The dynamic properties of the PLL are
under the control of the user through selection of the desired external components.

AZ12010 FUNCTIONAL PIN/PAD DESCRIPTIONS
Functional Description
Reference Frequency Input This pin/pad includes an on-chip 470 Ω pull
down resistor to VBB. The input from the reference circuit should be AC
coupled.
Reference Frequency Output This pin is an inverted and amplified version of
the signal on the REFIN pin. The gain from REFIN to ¯¯¯¯¯¯¯¯
REFOUT is
approximately 20. If VEEP is connected to VEE, a 4 ma on-chip current source is
provided for the output.
¯¯¯¯¯¯¯¯
REFOUT is not available on the packaged versions (AZ12010A, AZ12010B).
Charge Pump Reference Output The pin/pad voltage is nominally 1.2 volts
below VCC.
Charge Pump Output The charge pump output voltage is VCPREF ±0.3V
during a phase correction pulse. When there is no correction pulse the output
goes high impedance.
Charge Pump Polarity When this pin/pad is pulled high the PLL operates
with a VCSO circuit exhibiting negative pulling slope (the VCSO frequency
goes down when the control voltage goes up). When this pin/pad is pulled low
(AZM12010B) the PLL operates with a VCSO circuit exhibiting positive
pulling slope (the VCSO frequency goes up when the control voltage goes up).
If the pin/pad is left open (AZM12010A), an internal pullup resistor selects
negative pulling slope mode.
Integrator Reference Input This pin/pad should be connected to CPREF
through a bias current cancellation network
Integrator Summing Junction This pin/pad is the summing junction for the
integrator amplifier
Integrator Output
SAW Amplifier Inputs If only one input is used (Single-ended VCSO), the
unused input should be bypassed with a capacitor to VBB.
SAW Amplifier Outputs These are open collector outputs for driving the
VCSO device. Operating at nominally 9 ma, external pullup resistors must be
connected between these pins/pads and VCC. If only one output is used, the
other output should be connected to VCC through a 50Ω resistor.
PLL Output Enable The Q and Q
¯ outputs are enabled when this pin/pad is
pulled high. When this pin/pad is low, the Q output is high, and the Q
¯ output is
low. If the pin/pad is left open, an internal pullup resistor enables the outputs.
Divide Select When this pin/pad is high, the Q and Q
¯ outputs are divided by
one from the SAW device. When it is low, the Q and Q
¯ outputs are divided by
two from the SAW device. If the pin/pad is left open, an internal pullup resistor
selects the divide by one mode.
Clock Output These pin/pads are the main clock output. When ENABLE is
low, the outputs are disabled with Q high and Q
¯ low.
Reference Voltage Output This pin/pad is used to bias the REFIN signal. It
must be bypassed externally to the VEE pins/pads with a 0.01 μF capacitor.
REFOUT
¯¯¯¯¯¯¯¯ Current Source If VEEP is connected to VEE, a 4 ma on-chip current
source is provided for the ¯¯¯¯¯¯¯¯
REFOUT output.
VEEP is not available on the packaged versions (AZ12010A, AZ12010B).

Loop Filter Design
The combination of the phase detector, amplifier, VCO and divider form a second-order phase-locked loop. Proper
selection of the loop components is important to obtain stable, low jitter operation.
The loop bandwidth (or natural frequency, ωn) and damping factor (ζ) are the two major driving forces that define the
loop’s response to a disturbance. The value of ζ is typically 0.7 to ensure the fastest step response consistent with no
ringing. However in many oscillator application ζ may be 3 or higher to provide further phase noise reduction. ωn is
chosen as a compromise between settling time, VCO jitter and reference feedthrough. These values can be computed by
the following equations:
ωn =
ζ =
1
N
Kφ KVCO
τ1
τ 2ω n
2
τ 1 = R1C1
τ 2 = R2 C1
Kφ = Phase Detector Gain (20.3 radians/V)
KVCO = VCO Gain (radians/sec/volt)
N = Frequency Divisor value (32)
The component definitions are shown in the figure below. R3 should be equal to R1 to minimize integrator offsets.
