SW1 and SW2 are normally closed switches. SW3 is normally open. When power-down is initiated, SW3 is closed, and SW1 and SW2 are opened. This ensures that there is no loading of the REFIN pin on power-down.

A and B Counters SW3 NO 04414-0-010 BUFFER SW1 R COUNTER Figure 10. Reference Input Stage PRESCALER (P/P + 1) The dual-modulus prescaler (P/P + 1), along with the A and B counters, enables the large division ratio, N, to be realized (N = BP + A). The dual-modulus prescaler, operating at CML levels, takes the clock from the VCO and divides it down to a manageable frequency for the CMOS A and B counters. The prescaler is programmable. It can be set in software to 8/9, 16/17, or 32/33 and is based on a synchronous 4/5 core. There is a minimum divide ratio possible for fully contiguous output frequencies; this minimum is determined by P, the prescaler value, and is given by (P2 − P). A AND B COUNTERS The 14-bit R counter allows the input reference frequency to be divided down to produce the reference clock to the phase frequency detector (PFD). Division ratios from 1 to 16,383 are allowed. PFD AND CHARGE PUMP The PFD takes inputs from the R counter and N counter (N = BP + A) and produces an output proportional to the phase and frequency difference between them. Figure 12 is a simplified schematic. The PFD includes a programmable delay element that controls the width of the antibacklash pulse. This pulse ensures that there is no dead zone in the PFD transfer function and minimizes phase noise and reference spurs. Two bits in the R counter latch, ABP2 and ABP1, control the width of the pulse (see Table 9). The A and B CMOS counters combine with the dual-modulus prescaler to allow a wide range division ratio in the PLL feedback counter. The counters are specified to work when the prescaler output is 300 MHz or less. Thus, with a VCO frequency of 2.5 GHz, a prescaler value of 16/17 is valid, but a value of 8/9 is not valid. VP HI D1 Q1 CHARGE PUMP UP U1 R DIVIDER CLR1 Pulse Swallow Function PROGRAMMABLE DELAY The A and B counters, in conjunction with the dual-modulus prescaler, make it possible to generate output frequencies that are spaced only by the reference frequency divided by R.

P is the preset modulus of the dual-modulus prescaler (8/9, 16/17, and so on). B is the preset divide ratio of the binary 13-bit counter (3 to 8191). A is the preset divide ratio of the binary 5-bit swallow counter (0 to 31). fREFIN is the external reference frequency oscillator. CPGND R DIVIDER N DIVIDER CP OUTPUT Figure 12.

C2 and C1 Truth Table The output multiplexer on the ADF4360 family allows the user to access various internal points on the chip. The state of MUXOUT is controlled by M3, M2, and M1 in the function latch. The full truth table is shown in Table 7. Figure 13 shows the MUXOUT section in block diagram form. Lock Detect MUXOUT can be programmed for two types of lock detect: digital and analog. Digital lock detect is active high. When LDP in the R counter latch is set to 0, digital lock detect is set high when the phase error on three consecutive phase detector cycles is less than 15 ns. With LDP set to 1, five consecutive cycles of less than 15 ns phase error are required to set the lock detect. It stays set high until a phase error of greater than 25 ns is detected on any subsequent PD cycle. The N-channel open-drain analog lock detect should be operated with an external pull-up resistor of 10 kΩ nominal. When a lock has been detected, this output is high with narrow lowgoing pulses. DVDD Control Bits C1 0 1 0 1 C2 0 0 1 1 Control Latch R Counter N Counter (A and B) Test Modes Latch VCO The VCO core in the ADF4360 family uses eight overlapping bands, as shown in Figure 14, to allow a wide frequency range to be covered without a large VCO sensitivity (KV) and resultant poor phase noise and spurious performance. The correct band is chosen automatically by the band select logic at power-up or whenever the N counter latch is updated. It is important that the correct write sequence be followed at power-up. This sequence is 1. R counter latch 2. Control latch 3. N counter latch During band select, which takes five PFD cycles, the VCO VTUNE is disconnected from the output of the loop filter and connected to an internal reference voltage.

MUXOUT Circuit INPUT SHIFT REGISTER 1.7 1.5 1.3 1.1 The ADF4360 family’s digital section includes a 24-bit input shift register, a 14-bit R counter, and an 18-bit N counter, comprised of a 5-bit A counter and a 13-bit B counter. Data is clocked into the 24-bit shift register on each rising edge of CLK. The data is clocked in MSB first. Data is transferred from the shift register to one of four latches on the rising edge of LE. The destination latch is determined by the state of the two control bits (C2, C1) in the shift register. These are the two LSBs, DB1 and DB0, as shown in Figure 2. The truth table for these bits is shown in Table 5. Table 6 shows a summary of how the latches are programmed. Note that the test modes latch is used for factory testing and should not be programmed by the user. 0.9 04644-0-004 R COUNTER OUTPUT 0.7 0.5 2200 2400 2600 FREQUENCY (MHz) 2800 3000 Figure 14. Frequency vs. VTUNE, ADF4360-0 The R counter output is used as the clock for the band select logic and should not exceed 1 MHz. A programmable divider is provided at the R counter input to allow division by 1, 2, 4, or 8 and is controlled by Bits BSC1 and BSC2 in the R counter latch. Where the required PFD frequency exceeds 1 MHz, the divide ratio should be set to allow enough time for correct band selection. After band select, normal PLL action resumes. The nominal value of KV is 56 MHz/V or 28 MHz/V, if divide-by-2 operation has been selected (by programming DIV2 (DB22) high in the N counter latch). The ADF4360 family contains linearization circuitry to minimize any variation of the product of ICP and KV. Rev. 0 | Page 10 of 20 ADF4360-0 OUTPUT STAGE The RFOUTA and RFOUTB pins of the ADF4360 family are connected to the collectors of an NPN differential pair driven by buffered outputs of the VCO, as shown in Figure 15. To allow the user to optimize the power dissipation versus the output power requirements, the tail current of the differential pair is programmable via Bits PL1 and PL2 in the control latch. Four current levels may be set: +3.5 mA, +5 mA, +7.5 mA, and +11 mA. These levels give output power levels of −13 dBm, −11 dBm, −8.5 dBm, and −6.5 dBm, respectively, using a 50 Ω resistor to VDD and ac coupling into a 50 Ω load. Alternatively, both outputs can be combined in a 1 + 1:1 transformer or a 180° microstrip coupler (see the Output Matching section). If the outputs are used individually, the optimum output stage consists of a shunt inductor to VDD. Another feature of the ADF4360 family is that the supply current to the RF output stage is shut down until the part achieves lock as measured by the digital lock detect circuitry. This is enabled by the Mute-Till-Lock Detect (MTLD) bit in the control latch. Rev. 0 | Page 11 of 20 RFOUTA VCO RFOUTB BUFFER/ DIVIDE BY 2 04414-0-015 The operating current in the VCO core is programmable in four steps: 5 mA, 10 mA, 15 mA, and 20 mA. This is controlled by Bits PC1 and PC2 in the control latch. Figure 15. Output Stage ADF4360-0 ADF4360-0 LATCH STRUCTURE Table 6 shows the three on-chip latches for the ADF4360 family.

Table 7 shows the input data format for programming the control latch. Charge Pump Currents Prescaler Value CPI3, CPI2, and CPI1 in the ADF4360 family determine Current Setting 1. In the ADF4360 family, P2 and P1 in the control latch set the prescaler values. CPI6, CPI5, and CPI4 determine Current Setting 2. See the truth table in Table 7. Power-Down Output Power Level DB21 (PD2) and DB20 (PD1) provide programmable powerdown modes. Bits PL1 and PL2 set the output power level of the VCO. See the truth table in Table 7. In the programmed asynchronous power-down, the device powers down immediately after latching a 1 into Bit PD1, with the condition that PD2 has been loaded with a 0. In the programmed synchronous power-down, the device power-down is gated by the charge pump to prevent unwanted frequency jumps. Once the power-down is enabled by writing a 1 into Bit PD1 (on the condition that a 1 has also been loaded to PD2), the device goes into power-down on the second rising edge of the R counter output, after LE goes high. When the CE pin is low, the device is immediately disabled regardless of the state of PD1 or PD2. Mute-Till-Lock Detect When a power-down is activated (either synchronous or asynchronous mode), the following events occur: DB11 of the control latch in the ADF4360 family is the Mute-TillLock Detect bit. This function, when enabled, ensures that the RF outputs are not switched on until the PLL is locked. CP Gain DB10 of the control latch in the ADF4360 family is the Charge Pump Gain bit. When it is programmed to a 1, Current Setting 2 is used. When it is programmed to a 0, Current Setting 1 is used. Charge Pump Three-State This bit puts the charge pump into three-state mode when programmed to a 1. It should be set to 0 for normal operation. Phase Detector Polarity The PDP bit in the ADF4360 family sets the phase detector polarity. The positive setting enabled by programming a 1 is used when using the on-chip VCO with a passive loop filter or with an active non-inverting filter. It can also be set to 0. This is required, if an active inverting loop filter is used. • All active dc current paths are removed. • The R, N, and timeout counters are forced to their load state conditions. • The charge pump is forced into three-state mode. MUXOUT Control • The digital lock detect circuitry is reset. The on-chip multiplexer is controlled by M3, M2, and M1. See the truth table in Table 7. • The RF outputs are debiased to a high impedance state. Counter Reset • The reference input buffer circuitry is disabled. • The input register remains active and capable of loading and latching data. DB4 is the counter reset bit for the ADF4360 family. When this is 1, the R counter and the A, B counters are reset. For normal operation, this bit should be 0. Core Power Level PC1 and PC2 set the power level in the VCO core. The recommended setting is 10 mA. See the truth table in Table 7. Rev. 0 | Page 16 of 20 ADF4360-0 N COUNTER LATCH R COUNTER LATCH With (C2, C1) = (1, 0), the N counter latch is programmed. Table 8 shows the input data format for programming the N counter latch. With (C2, C1) = (0, 1), the R counter latch is programmed. Table 9 shows the input data format for programming the R counter latch. A Counter Latch R Counter A5 to A1 program the 5-bit A counter. The divide range is 0 (00000) to 31 (11111). R1 to R14 set the counter divide ratio. The divide range is 1 (00......001) to 16383 (111......111). Reserved Bits Antibacklash Pulse Width DB7 is a spare bit and has been designated as Reserved. It should be programmed to 0. DB16 and DB17 set the antibacklash pulse width. B Counter Latch DB18 is the lock detect precision bit. This bit sets the number of reference cycles with less than 15 ns phase error for entering the locked state. With LDP at 1, five cycles are taken; with LDP at 0, three cycles are taken. Lock Detect Precision B13 to B1 program the B counter. The divide range is 3 (00.....0011) to 8191 (11....111). Overall Divide Range The overall divide range is defined by ((P × B) + A), where P is the prescaler value. CP Gain DB21 of the N counter latch in the ADF4360 family is the charge pump gain bit. When this is programmed to 1, Current Setting 2 is used. When programmed to 0, Current Setting 1 is used. This bit can also be programmed through DB10 of the control latch. The bit always reflects the latest value written to it, whether this is through the control latch or the N counter latch. Divide-by-2 DB22 is the divide-by-2 bit. When set to 1, the output divide-by-2 function is chosen. When it is set to 0, normal operation occurs. Divide-by-2 Select Test Mode Bit DB19 is the test mode bit (TMB) and should be set to 0. With TMB = 0, the contents of the test mode latch are ignored and normal operation occurs as determined by the contents of the control latch, R counter latch, and N counter latch. Note that test modes are for factory testing only and should not be programmed by the user. Band Select Clock These bits set a divider for the band select logic clock input. The output of the R counter is by default the value used to clock the band select logic, but, if this value is too high (>1 MHz), a divider can be switched on to divide the R counter output to a smaller value (see Table 9). Reserved Bits DB23 is the divide-by-2 select bit. When programmed to 1, the divide-by-2 output is selected as the prescaler input. When set to 0, the fundamental is used as the prescaler input. For example, using the output divide-by-2 feature and a PFD frequency of 200 kHz, the user needs a value of N = 13,000 to generate 1,500 MHz. With the divide-by-2 select bit high, the user may keep N = 6,500. DB23 to DB22 are spare bits that have been designated as Reserved. They should be programmed to 0. Rev. 0 | Page 17 of 20 ADF4360-0 APPLICATIONS ADuC812 Interface Figure 16 shows the ADF4360-0 used as a fixed frequency LO at 2.6 GHz. The low-pass filter was designed using ADIsimPLL for a channel spacing of 8 MHz and an open-loop bandwidth of 40 kHz. The maximum PFD frequency of the ADF4360-0 is 8 MHz. Since using a larger PFD frequency allows users to use a smaller N, the in-band phase noise is reduced to as low as possible, –100 dBc/Hz. The 40 kHz bandwidth is chosen to be just greater than the point at which the open-loop phase noise of the VCO is –100 dBc/Hz, thus giving the best possible integrated noise. The typical rms phase noise (100 Hz to 100 kHz) of the LO in this configuration is 0.35°. The reference frequency is from a 16 MHz TCXO from Fox; thus, an R value of 2 is programmed. Taking into account the high PFD frequency and its effect on the band select logic, the band select clock divider is enabled. In this case, a value of 8 is chosen. A very simple pull-up resistor and dc blocking capacitor complete the RF output stage. 6 10µF FOX 801BE-160 16MHz 2 23 3kΩ 8.2nF 560pF ADF4360-0 12 CC 51Ω 13 RSET 51Ω 100pF RFOUTA 4 4.7kΩ AGND 3 8 9 10 LE I/O PORTS ADF4360-x CE MUXOUT (LOCK DETECT) 22 15 I/O port lines on the ADuC812 are also used to control powerdown (CE input) and detect lock (MUXOUT configured as lock detect and polled by the port input). When operating in the described mode, the maximum SCLOCK rate of the ADuC812 is 4 MHz. This means that the maximum rate at which the output frequency can be changed is 166 kHz.

Fixed Frequency LO POWER-UP Figure 18 shows the interface between the ADF4360 family and the ADSP-21xx digital signal processor. The ADF4360 family needs a 24-bit serial word for each latch write. The easiest way to accomplish this using the ADSP-21xx family is to use the autobuffered transmit mode of operation with alternate framing. This provides a means for transmitting an entire block of serial data before an interrupt is generated. After power-up, the part needs three writes for normal operation. The correct sequence is to the R counter latch, followed by the control latch, and N counter latch. SCLOCK MOSI TFS INTERFACING ADSP-21xx The ADF4360 family has a simple SPI® compatible serial interface for writing to the device. CLK, DATA, and LE control the data transfer. When LE goes high, the 24 bits that have been clocked into the appropriate register on each rising edge of CLK are transferred to the appropriate latch. See Figure 2 for the timing diagram and Table 5 for the latch truth table. The maximum allowable serial clock rate is 20 MHz. This means that the maximum update rate possible is 833 kHz or one update every 1.2 µs. This is more than adequate for systems that have typical lock times in hundreds of microseconds. I/O PORTS SCLK SDATA LE ADF4360-x CE MUXOUT (LOCK DETECT) 04437-0-015 VVCO Figure 17 shows the interface between the ADF4360 family and the ADuC812 MicroConverter®. Since the ADuC812 is based on an 8051 core, this interface can be used with any 8051 based microcontroller. The MicroConverter is set up for SPI master mode with CPHA = 0. To initiate the operation, the I/O port driving LE is brought low. Each latch of the ADF4360 family needs a 24-bit word, which is accomplished by writing three 8bit bytes from the MicroConverter to the device. When the third byte has been written, the LE input should be brought high to complete the transfer. 04437-0-014 FIXED FREQUENCY LO Figure 18. ADSP-21xx to ADF4360-x Interface Set up the word length for 8 bits and use three memory locations for each 24-bit word. To program each 24-bit latch, store the 8-bit bytes, enable the autobuffered mode, and write to the transmit register of the DSP. This last operation initiates the autobuffer transfer. Rev. 0 | Page 18 of 20 ADF4360-0 The leads on the chip scale package (CP-24) are rectangular. The printed circuit board pad for these should be 0.1 mm longer than the package lead length and 0.05 mm wider than the package lead width. The lead should be centered on the pad to ensure that the solder joint size is maximized. Experiments have shown that the circuit shown in Figure 20 provides an excellent match to 50 Ω over the operating range of the ADF4360-0. This gives approximately −4 dBm output power across the frequency range of the ADF4360-0. Both singleended architectures can be examined using the EVALADF4360-0EB1 evaluation board. VVCO The bottom of the chip scale package has a central thermal pad. The thermal pad on the printed circuit board should be at least as large as this exposed pad. On the printed circuit board, there should be a clearance of at least 0.25 mm between the thermal pad and the inner edges of the pad pattern to ensure that shorting is avoided. 47nH 1.5pF 3.9nH RFOUT 50Ω 04414-0-021 PCB DESIGN GUIDELINES FOR CHIP SCALE PACKAGE Figure 20. Differential ADF4360-0 Output Stage If the user does not need the differential outputs available on the ADF4360-0, the user may either terminate the unused output or combine both outputs using a balun. The circuit in Figure 21 shows how best to combine the outputs. VVCO The user should connect the printed circuit thermal pad to AGND. This is internally connected to AGND. 1nH RFOUTA OUTPUT MATCHING There are a number of ways to match the output of the ADF4360-0 for optimum operation; the most basic is to use a 50 Ω resistor to VVCO. A dc bypass capacitor of 100 pF is connected in series, as shown in Figure 19. Because the resistor is not frequency dependent, this provides a good broadband match. The output power in the circuit below typically gives −6.5 dBm output power into a 50 Ω load. VVCO 51Ω 50Ω 04414-0-020 100pF RFOUT Figure 19. Simple ADF4360-1 Output Stage A better solution is to use a shunt inductor (acting as an RF choke) to VVCO. This gives a better match than a resistor and, therefore, more output power. Additionally, a series inductor is added after the dc bypass capacitor to provide a resonant LC circuit. This tunes the oscillator output and provides approximately 10 dB additional rejection of the second harmonic. The shunt inductor needs to be a relatively low value (<10 nH). 3.6nH 47nH 1.5pF 10pF 3.6nH RFOUTB 50Ω 1nH 1.5pF 04414-0-022 Thermal vias may be used on the printed circuit board thermal pad to improve thermal performance of the package. If vias are used, they should be incorporated in the thermal pad at 1.2 mm pitch grid. The via diameter should be between 0.3 mm and 0.33 mm, and the via barrel should be plated with 1 ounce of copper to plug the via. Figure 21. Balun for Combining ADF4360-0 RF Outputs The circuit in Figure 21 is a lumped lattice type LC balun. It is designed for a center frequency of 2.6 GHz and outputs −1 dBm at this frequency. The series 1 nH inductor is used to tune out any parasitic capacitance due to the board layout from each input, and the remainder of the circuit is used to shift the output of one RF input by +90° and the second by −90°, thus combining the two. The action of the 3.6 nH inductor and the 1.5 pF capacitor accomplishes this. The 12 nH is used to provide an RF choke to feed the supply voltage, and the 10 pF capacitor provides the necessary dc block. To ensure good RF performance, the circuits in Figure 19 and Figure 21 are implemented with Coilcraft 0402/0603 inductors and AVX 0402 thin-film capacitors. Alternatively, instead of the LC balun shown in Figure 21, both outputs may be combined using a 180° rat-race coupler.
