Replacement verdict
Compatible functional replacement candidate
The ADF4107BRU and ADF4113BRU-REEL7 are both single PLL frequency synthesizers from Analog Devices in the same 16-lead TSSOP package, sharing a common pinout and 3 V supply architecture, so the ADF4113BRU-REEL7 can serve as a functional replacement candidate for the ADF4107BRU where the lower maximum operating frequency is acceptable. Designers should validate the reduced RF input bandwidth and confirm the specific frequency plan before substituting in production.

Key electrical and mechanical differences between the two devices
| Parameter | ADF4107BRU | ADF4113BRU-REEL7 | Why it matters |
|---|---|---|---|
| Maximum RF Input Frequency | 7 GHz | 4 GHz | Determines the highest frequency the PLL synthesizer can operate at; the ADF4107 supports higher-frequency applications than the ADF4113. |
| RF Input Frequency Range (minimum) | 0.5 GHz | 0.2 GHz | Defines the lowest usable RF input; the ADF4113 can lock to lower frequencies, affecting low-band coverage. |
| Maximum PFD (Phase Frequency Detector) Frequency | 104 MHz | 55 MHz | Higher PFD frequency enables wider loop bandwidth and faster settling; the ADF4107 allows a higher reference comparison rate. |
| Normalized Phase Noise Floor | -219 dBc/Hz | -211 dBc/Hz | Lower phase noise floor yields cleaner synthesized signals; the ADF4107 offers better noise performance for sensitive RF designs. |
| Maximum RF Input Frequency (prescaler) | 7 GHz | 4 GHz | The integrated prescaler limits the maximum input frequency; this constrains which bands each synthesizer can support. |
| Supply Voltage Range | 2.7 V to 3.3 V | 2.7 V to 3.3 V | Both operate over the same supply range, so power-rail compatibility is equivalent between the two parts. |
| Package | 16-Lead TSSOP | 16-Lead TSSOP | Identical package and pinout allow drop-in board compatibility without layout changes. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Matching temperature ratings mean equivalent environmental robustness for industrial applications. |
| Number of Programmable Counters / Modulus | Dual-modulus prescaler (8/9, 16/17, 32/33, 64/65) | Dual-modulus prescaler (8/9, 16/17, 32/33, 64/65) | Same prescaler options provide equivalent frequency synthesis flexibility and loop configuration. |

Frequently asked questions
What are the key differences between the ADF4107BRU and ADF4113BRU-REEL7?
The ADF4107BRU is a 7 GHz fractional-N PLL frequency synthesizer, while the ADF4113BRU-REEL7 is a 4 GHz integer-N PLL frequency synthesizer. The ADF4107 supports fractional-N operation for finer frequency resolution, whereas the ADF4113 uses integer-N architecture. Both are offered in 16-lead TSSOP packages, but they differ in maximum RF input frequency and synthesizer architecture.
What is the maximum RF input frequency for each device?
The ADF4107BRU supports an RF input frequency up to 7 GHz. The ADF4113BRU-REEL7 supports an RF input frequency up to 4 GHz. These values are specified in the respective Analog Devices datasheets.
Do the ADF4107BRU and ADF4113BRU-REEL7 use the same package and pinout?
Both devices are supplied in a 16-lead TSSOP package. However, designers should verify pin function assignments against the respective datasheets, as the internal architecture (fractional-N versus integer-N) may result in different pin configurations or control signal requirements.
What is the difference between fractional-N and integer-N architecture in these parts?
The ADF4107BRU uses fractional-N architecture, which allows a fractional modulus for finer frequency step resolution and potentially lower phase noise trade-offs. The ADF4113BRU-REEL7 uses integer-N architecture, where the modulus is integer-based, typically resulting in simpler loop filter design but coarser frequency resolution for a given reference frequency.
Can the ADF4113BRU-REEL7 be used as a drop-in replacement for the ADF4107BRU?
No, they are not direct drop-in replacements. The ADF4107BRU operates up to 7 GHz with fractional-N architecture, while the ADF4113BRU-REEL7 operates up to 4 GHz with integer-N architecture. Differences in frequency range, synthesizer architecture, and register programming mean the replacement requires design validation against the target application and manufacturer documentation.
What supply voltage do these PLL synthesizers require?
Both the ADF4107BRU and ADF4113BRU-REEL7 operate from a nominal 3 V supply, with an operating range of 2.7 V to 3.3 V as specified in the Analog Devices datasheets. Designers should confirm the exact supply requirements and decoupling recommendations from the official datasheets.
What is the significance of the REEL7 suffix on the ADF4113BRU-REEL7?
The REEL7 suffix indicates tape-and-reel packaging for automated assembly, typically with a 7-inch reel. The base part, ADF4113BRU, is the same device; the suffix only denotes the packaging format for production handling.
