Product details
Overview
ADF4107BCP from Analog Devices is a 7 GHz bandwidth integer-N PLL frequency synthesizer designed for local oscillator generation in wireless transceivers. It integrates a low-noise phase frequency detector, programmable dual-modulus prescaler (8/9, 16/17, 32/33, 64/65), 14-bit R counter, and 19-bit N divider (6-bit A + 13-bit B counters). Operates from 2.7 V to 3.3 V with separate VP supply up to 5.5 V, enabling extended VCO tuning voltage in 3 V systems.
For engineers reviewing the ADF4107BCP datasheet, ADF4107BCP pinout, ADF4107BCP application, or ADF4107BCP equivalent, key selection criteria include RF input frequency range (1–7 GHz), charge pump current programmability (625 µA to 5 mA), antibacklash pulse width control, 3-wire serial interface timing compliance, and lock detect functionality (analog/digital).
Technical Context
The ADF4107BCP implements an integer-N PLL architecture with a dual-modulus prescaler driving cascaded A and B counters to realize N = BP + A division. Its PFD supports up to 104 MHz phase detector frequency and includes programmable antibacklash pulse width (1.3 ns, 2.9 ns, or 6.0 ns) to eliminate dead zone and suppress reference spurs.
It features separate analog (AVDD) and digital (DVDD) supplies tied at same voltage, dedicated charge pump power (VP ≥ AVDD), and a multiplexer output (MUXOUT) configurable for lock detect, scaled RF, or scaled reference signals - all controlled via 24-bit serial interface with latch-select control bits C2/C1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Input Frequency | 1.0 GHz to 7.0 GHz - supports direct up/downconversion LO synthesis without frequency doublers in high-band systems. |
| Phase Detector Freq | Up to 104 MHz - enables high-resolution channel spacing and fast lock times in wideband PLL designs. |
| Charge Pump Current | 625 µA to 5 mA (programmable) - sets loop filter gain and directly impacts PLL stability, settling time, and noise performance. |
| Prescaler Options | 8/9, 16/17, 32/33, 64/65 - determines minimum step size and frequency coverage continuity for given VCO range. |
| Reference Input Range | 20 MHz to 250 MHz - allows flexible crystal oscillator or buffered clock source selection with AC-coupled biasing. |
| Supply Voltages | AVDD/DVDD = 2.7–3.3 V; VP = AVDD to 5.5 V - decouples tuning voltage headroom from core logic, supporting 5 V-tuned VCOs in 3 V systems. |
| Lock Detect | Digital (3- or 5-cycle precision) and analog (open-drain) outputs - provides reliable PLL status monitoring for system-level fault detection and calibration sequencing. |
Pinout & Package
ADF4107BCP is housed in a 16-lead TSSOP (3 mm × 4.4 mm) package with exposed pad. Pin functions are electrically and thermally optimized for RF PLL applications: AGND/DGND separation minimizes digital noise coupling into analog paths; CPGND provides dedicated return for charge pump current; VP enables independent tuning voltage rail.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RSET | Charge pump current setting | Resistor-to-ground sets ICP max (5 mA typical with 5.1 kΩ); defines loop filter gain and dynamic range. |
| CP | Charge pump output | Drives external loop filter; bipolar ±ICP current source/sink; requires low-impedance path to VCO tuning port. |
| RFINA/RFINB | Differential RF input | Accepts 1–7 GHz signal; internal limiting amplifier converts to CML; requires 100 pF AC coupling and bias network. |
| REFIN | Reference clock input | CMOS input (VDD/2 threshold); supports 20–250 MHz; AC- or DC-coupled with 100 kΩ internal termination. |
| CLK/DATA/LE | 3-wire serial interface | 24-bit MSB-first shift register; LE latches data to R/N/function/initialization latches per C2/C1 control bits. |
| MUXOUT | Multiplexed diagnostic output | Selectable between lock detect, divided RF, or divided REFIN - enables real-time PLL health monitoring without external probes. |
Key Features
| Feature | Design Value |
|---|---|
| 7 GHz RF bandwidth | Enables direct synthesis of LMDS, satellite, and 5G FR2 LO signals without harmonic mixing or doublers. |
| Separate VP supply | Allows 5 V tuning voltage while maintaining 3 V core logic - extends VCO tuning range without level-shifting circuitry. |
| Programmable antibacklash pulse | Configurable 1.3/2.9/6.0 ns width eliminates PFD dead zone, reducing reference spurs and in-band phase noise. |
| Dual-modulus prescaler | Four selectable ratios (8/9 through 64/65) optimize N-divider resolution and frequency coverage for specific VCO bands. |
| Hardware/software power-down | CE pin and F2 bit enable low-quiescent-current mode (<10 µA), critical for battery-powered or duty-cycled RF systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PLL synthesizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADF4153ACPZ | Higher 4 GHz RF input limit; integrated LDO; no separate VP pin; lower max PFD frequency (50 MHz). | Better suited for compact 2.4/5 GHz WLAN radios where board space and supply count are constrained. | Select ADF4153ACPZ when integrated regulation and smaller footprint outweigh need for >4 GHz RF input or extended VP tuning range. |
| LMX2531LQ1580E | Fractional-N architecture; 2.5 GHz max RF input; integrated VCO; SPI interface; higher integration but fixed frequency bands. | Ideal for cost-sensitive consumer devices requiring single-chip LO solution below 2.5 GHz with fine frequency resolution. | Choose LMX2531LQ1580E for simplified design with on-chip VCO where 7 GHz bandwidth and external VCO flexibility are not required. |
Compared with ADF4107BCP, ADF4153ACPZ trades RF bandwidth and VP flexibility for integration and size, while LMX2531LQ1580E replaces integer-N programmability with fractional-N convenience and embedded VCO - making ADF4107BCP uniquely suited for high-frequency, externally tuned, low-noise LO systems.

FAQ
What is the maximum RF input frequency supported by the ADF4107BCP?
The ADF4107BCP supports an RF input frequency range of 1.0 GHz to 7.0 GHz, as specified in the Rev. D datasheet under RF CHARACTERISTICS. This 7 GHz bandwidth enables direct synthesis of LO signals for LMDS, satellite, and high-band 5G applications without requiring frequency doublers or harmonic mixers.
Does the ADF4107BCP require an external loop filter?
Yes, the ADF4107BCP requires an external passive loop filter connected between the CP pin and the tuning port of an external VCO. The charge pump output drives this filter to generate the VCO control voltage; loop filter design depends on selected ICP value, PFD frequency, and desired PLL bandwidth/stability.
How is the charge pump current configured on the ADF4107BCP?
The ADF4107BCP charge pump current is set by an external resistor (RSET) connected between the RSET pin and CPGND. With RSET = 5.1 kΩ, ICP MAX = 5 mA; the device supports programmable current scaling via CPI bits in the function latch, yielding values from 625 µA to 5 mA in discrete steps.
What package type is used for the ADF4107BCP?
The ADF4107BCP is packaged in a 16-lead TSSOP (Thin Shrink Small Outline Package) with dimensions 3 mm × 4.4 mm and exposed thermal pad. Pin configuration matches Figure 3 in the Rev. D datasheet, and the exposed pad must be soldered to AGND for thermal and electrical performance.
Can the ADF4107BCP operate with different analog and digital supply voltages?
No - the ADF4107BCP requires AVDD and DVDD to be at the same voltage level (2.7 V to 3.3 V), as explicitly stated in the POWER SUPPLIES section of the datasheet. However, VP may be independently set from AVDD up to 5.5 V to extend VCO tuning range without affecting core logic operation.
