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. 1630 S.

AZ12010 FUNCTIONAL PIN/PAD DESCRIPTIONS Functional Description Reference Frequency Input This pin/pad includes an on-chip 470 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 is REFOUT approximately 20. If VEEP is connected to VEE, a 4 ma on-chip current source is provided for the output. is not available on the packaged versions (AZ12010A, AZ12010B). REFOUT 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 50 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 F capacitor. REFOUT Current Source If VEEP is connected to VEE, a 4 ma on-chip current source is provided for the output. REFOUT VEEP is not available on the packaged versions (AZ12010A, AZ12010B). Positive Supply +3.0 to +3.6 V Negative Supply Ground

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, n) and damping factor () are the two major driving forces that define the loop's response to a disturbance. The value of is typically 0.7 to ensure the fastest step response consistent with no ringing. However in many oscillator application may be 3 or higher to provide further phase noise reduction. n is chosen as a compromise between settling time, VCO jitter and reference feedthrough. These values can be computed by the following equations:
n =
1 N
K KVCO
1
=
2 n
2
1 = R1C1 2 = R2 C1
K = 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.
