Key electrical and mechanical differences between the two devices
| Parameter | ADF4106BRU | ADF4106SRU-EP | Why it matters |
|---|---|---|---|
| Function | PLL Frequency Synthesizer (integer-N) | PLL Frequency Synthesizer (integer-N) | Both devices perform the same core function, so they are functionally interchangeable in synthesizer designs. |
| Maximum RF Input Frequency | 6 GHz | 6 GHz | Determines the highest frequency the prescaler/PLL can accept; identical limits mean the same RF range is supported. |
| Supply Voltage Range | 2.7 V to 3.3 V | 2.7 V to 3.3 V | Both operate from the same supply window, so power supply design does not need to change between parts. |
| Package | 16-Lead TSSOP | 16-Lead TSSOP | Identical package and pinout allow drop-in board replacement without layout changes. |
| Operating Temperature Range | -40 °C to +85 °C | -55 °C to +125 °C | The EP version supports extended temperature operation, which matters for harsh-environment or military/aerospace applications. |
| Grade / Screening | Standard commercial/industrial grade | Enhanced Product (EP) grade | The EP grade is screened and qualified for higher reliability and wider temperature, affecting suitability for mission-critical designs. |
| Interface | 3-wire serial (SPI-compatible) | 3-wire serial (SPI-compatible) | Same programming interface means firmware and microcontroller connections remain compatible. |
| Prescaler | Dual-modulus 8/9, 16/17, 32/33, 64/65 | Dual-modulus 8/9, 16/17, 32/33, 64/65 | Identical prescaler options ensure the same loop and frequency planning can be reused. |
| Charge Pump Current | Programmable (up to 5 mA) | Programmable (up to 5 mA) | Same charge pump capability allows identical loop filter design and lock performance. |

Frequently asked questions
What are the key differences between the ADF4106BRU and ADF4106SRU-EP?
The ADF4106BRU is the standard industrial-grade version of the ADF4106 PLL frequency synthesizer in a 16-lead TSSOP package, specified over the -40°C to +85°C temperature range. The ADF4106SRU-EP is the enhanced-product (EP) variant, which is screened and qualified for extended temperature operation up to +105°C (or higher, per the EP datasheet) and is intended for applications requiring enhanced reliability and wider thermal margins. Both share the same core PLL architecture, 6 GHz RF input bandwidth, and 16-lead TSSOP footprint.
Are the ADF4106BRU and ADF4106SRU-EP pin-compatible and footprint-compatible?
Yes. Both devices are offered in the same 16-lead TSSOP (RU-16) package with identical pin assignments, so they are pin-to-pin and footprint-compatible. This allows the EP variant to be used as a drop-in replacement on an existing ADF4106BRU PCB layout, provided the extended temperature and reliability requirements are validated for the application.
What is the maximum RF input frequency for both devices?
Both the ADF4106BRU and ADF4106SRU-EP support an RF input bandwidth of up to 6 GHz, making them suitable for high-frequency PLL synthesizer designs in wireless infrastructure, instrumentation, and microwave applications.
Do the ADF4106BRU and ADF4106SRU-EP have the same supply voltage and current consumption?
Yes. Both devices operate from a 2.7 V to 3.3 V supply and feature a typical supply current of approximately 11 mA (per the ADF4106 datasheet). The EP variant maintains the same electrical core specifications while adding enhanced screening and extended temperature qualification.
What is the operating temperature range difference between the two parts?
The ADF4106BRU is specified for the standard industrial temperature range of -40°C to +85°C. The ADF4106SRU-EP is qualified for an extended temperature range (typically -40°C to +105°C, per the EP datasheet), making it preferable for applications exposed to higher thermal stress or requiring enhanced reliability screening.
Can the ADF4106SRU-EP be used as a direct substitute for the ADF4106BRU in an existing design?
In most cases yes, because both share the same package, pinout, supply voltage, and core PLL specifications. However, the substitution should be validated against the target design's thermal, reliability, and qualification requirements, and the EP datasheet should be reviewed to confirm any screening or specification differences relevant to the application.
What is the significance of the "EP" suffix on the ADF4106SRU-EP?
The "EP" suffix denotes the enhanced-product variant, which is subjected to additional screening and qualification for extended temperature operation and enhanced reliability. This makes the ADF4106SRU-EP suitable for applications such as industrial, automotive-adjacent, or high-reliability systems where the standard ADF4106BRU industrial grade may not provide sufficient thermal margin.
