Replacement verdict
Compatible functional replacement candidate
The ADF4106BRUZ and ADF4110BRUZ are both single PLL frequency synthesizers from the same family, sharing an identical 16-lead TSSOP footprint and a common 2.7 V to 3.3 V supply range, so they can serve as functional replacement candidates in many designs. However, the ADF4110BRUZ offers a higher maximum RF input frequency and a wider operating temperature range, while the ADF4106BRUZ provides a lower typical supply current. Designers should validate RF frequency requirements, thermal margin, and power budget before substituting one for the other.

Key electrical and mechanical differences between the two devices
| Parameter | ADF4106BRUZ | ADF4110BRUZ | Why it matters |
|---|---|---|---|
| Maximum RF Input Frequency | 6 GHz | 550 MHz | Defines the highest frequency the PLL can lock to; the ADF4106 supports much higher frequency operation, so it is not a drop-in replacement for higher-band designs. |
| Maximum PFD Frequency | 104 MHz | 55 MHz | The phase frequency detector rate limits loop bandwidth and phase noise performance; a lower PFD ceiling restricts achievable settling and noise characteristics. |
| Normalized Phase Noise Floor | -219 dBc/Hz | -211 dBc/Hz | Lower normalized phase noise yields cleaner synthesized signals; the ADF4106 offers roughly 8 dB better noise floor, affecting spectral purity in sensitive RF systems. |
| RF Input Sensitivity Range | -10 dBm to +5 dBm (approx.) | -5 dBm to +5 dBm (approx.) | Determines the input power window the prescaler can reliably count; differing sensitivity affects compatibility with the VCO output level in a given design. |
| Supply Current (Typical) | 11 mA | 4.5 mA | Affects power budget and thermal design; the ADF4110 draws significantly less current, which matters in power-sensitive portable applications. |
| Prescaler | Dual-modulus 8/9, 16/17, 32/33, 64/65 | Dual-modulus 8/9, 16/17, 32/33, 64/65 | The prescaler options determine achievable division ratios and channel spacing; identical options here support similar loop configurations. |
| Package | 16-Lead TSSOP | 16-Lead TSSOP | Package and pinout compatibility is essential for physical board-level substitution; matching TSSOP packages ease layout reuse. |
| Supply Voltage Range | 2.7 V to 3.3 V | 2.7 V to 3.3 V | Operating voltage must match the system rail; identical ranges allow the same power supply design to be used for either part. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range defines environmental suitability; matching industrial ranges means both parts fit the same application envelope. |

Frequently asked questions
What is the primary functional difference between the ADF4106BRUZ and ADF4110BRUZ?
Both are integer-N PLL frequency synthesizers, but the ADF4106BRUZ operates up to 6 GHz while the ADF4110BRUZ operates up to 550 MHz. The ADF4106BRUZ is intended for higher-frequency RF applications, whereas the ADF4110BRUZ targets lower-frequency designs.
Are the ADF4106BRUZ and ADF4110BRUZ pin-compatible?
Yes. Both devices are offered in a 16-lead TSSOP package (RUZ suffix) with the same pinout, allowing a common PCB footprint. However, pin compatibility does not guarantee electrical or functional interchangeability in a given design.
What is the maximum RF input frequency for each device?
The ADF4106BRUZ has a maximum RF input frequency of 6 GHz. The ADF4110BRUZ has a maximum RF input frequency of 550 MHz.
Do both devices use the same supply voltage range?
Yes. Both the ADF4106BRUZ and ADF4110BRUZ operate from a 2.7 V to 3.3 V supply.
Can the ADF4110BRUZ be used as a drop-in replacement for the ADF4106BRUZ?
No. Although they share the same package and pinout, the ADF4110BRUZ is limited to 550 MHz and cannot cover the 6 GHz range of the ADF4106BRUZ. A replacement is only valid if the target design operates within the ADF4110BRUZ frequency and performance limits.
What is the maximum phase detector frequency for these devices?
Both the ADF4106BRUZ and ADF4110BRUZ support a maximum phase detector frequency of 55 MHz.
Do both devices support the same serial interface for programming?
Yes. Both the ADF4106BRUZ and ADF4110BRUZ use a 3-wire serial interface (CLK, DATA, LE) for register programming.
What is the difference in power consumption between the two devices?
The ADF4106BRUZ typically draws about 13 mA from a 3 V supply, while the ADF4110BRUZ typically draws about 4.5 mA from a 3 V supply. The lower-frequency ADF4110BRUZ consumes less current.
