Replacement verdict
Compatible functional replacement candidate
The ADF4113BRUZ and ADF4110BRUZ are both single-channel integer-N PLL frequency synthesizers from Analog Devices in the same 16-lead TSSOP package, sharing an identical pinout, supply range, and three-wire serial interface. They differ primarily in maximum RF input frequency and programmable prescaler range, so the ADF4113BRUZ can serve as a higher-frequency functional substitute for the ADF4110BRUZ where the target RF band and loop filter design remain within the ADF4110BRUZ's original specification. Designers should confirm RF input frequency, prescaler ratio, and charge pump current settings against the specific application before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | ADF4113BRUZ | ADF4110BRUZ | Why it matters |
|---|---|---|---|
| Maximum RF Input Frequency | 4.0 GHz | 550 MHz | Determines the highest frequency the PLL synthesizer can operate at; the ADF4113 supports much higher frequency bands than the ADF4110. |
| Prescaler | 8/9, 16/17, 32/33, 64/65 | 8/9, 16/17, 32/33, 64/65 | The dual-modulus prescaler affects the achievable division ratios and loop performance; both devices offer the same selectable prescaler options. |
| Supply Voltage Range | 2.7 V to 3.3 V | 2.7 V to 3.3 V | Defines the operating voltage window; both parts share the same 2.7 V to 3.3 V range, allowing similar power supply design. |
| Normalized Phase Noise Floor | -219 dBc/Hz | -219 dBc/Hz | Indicates the intrinsic phase noise performance of the synthesizer; identical values mean comparable spectral purity. |
| Maximum PFD Frequency | 55 MHz | 55 MHz | Sets the maximum phase frequency detector rate, influencing loop bandwidth and settling time; both parts share the same limit. |
| Package | 16-Lead TSSOP | 16-Lead TSSOP | Package type affects PCB footprint and thermal characteristics; both use the same 16-lead TSSOP for drop-in compatibility. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Defines the environmental operating window; identical ranges ensure equivalent reliability across applications. |
| Charge Pump Current (Programmable) | 0.625 mA to 5 mA | 0.625 mA to 5 mA | Charge pump current affects loop gain and lock time; both devices offer the same programmable range. |

Frequently asked questions
What are the key differences between the ADF4113BRUZ and ADF4110BRUZ?
Both are single PLL frequency synthesizers from Analog Devices in a 16-lead TSSOP package, but they differ in maximum RF operating frequency and prescaler. The ADF4113BRUZ operates up to 4.0 GHz with a 4/5 prescaler, while the ADF4110BRUZ operates up to 550 MHz with an 8/9 prescaler. Both integrate a low-noise digital phase frequency detector, programmable charge pump, and dual modulus prescaler.
Are the ADF4113BRUZ and ADF4110BRUZ pin-compatible?
Yes. Both devices are offered in the same 16-lead TSSOP (RU-16) package with identical pin assignments, allowing a common PCB footprint. However, pin compatibility does not guarantee functional interchangeability, since RF frequency range and prescaler settings differ.
What is the maximum RF input frequency for each device?
The ADF4113BRUZ supports RF input frequencies up to 4.0 GHz. The ADF4110BRUZ supports RF input frequencies up to 550 MHz. Designs must select the device whose upper frequency limit covers the intended VCO or reference signal range.
What prescaler does each device use?
The ADF4113BRUZ uses a 4/5 dual-modulus prescaler, while the ADF4110BRUZ uses an 8/9 dual-modulus prescaler. The prescaler value affects the programmable divider range and must be accounted for in loop filter and register configuration.
Do both devices share the same supply voltage and interface?
Yes. Both operate from a 2.7 V to 3.3 V supply and use a 3-wire serial interface (CLK, DATA, LE) for programming the on-chip registers. The charge pump supply (Vp) can be set independently to support a wider tuning voltage range.
Can the ADF4113BRUZ directly replace the ADF4110BRUZ in an existing design?
Not without validation. Although the package and pinout match, the higher 4.0 GHz RF range and 4/5 prescaler of the ADF4113BRUZ require re-checking the programmable divider settings, loop filter design, and register configuration against the target frequency plan. The replacement should only be made after confirming all parameters against the respective Analog Devices datasheets.
What is the typical phase noise performance of these synthesizers?
Both devices are specified with a normalized phase noise floor of approximately -219 dBc/Hz (PN1Hz) in their datasheets, enabling low phase noise in closed-loop PLL designs. Actual in-circuit phase noise depends on the VCO, loop filter, reference source, and charge pump current settings.
