Product details
Overview
ADF4110BRU-REEL7 from Analog Devices is a 550 MHz RF PLL frequency synthesizer IC used as a local oscillator in wireless transceiver up/downconversion stages. It features a 24-bit programmable N-divider (N = BP + A), 14-bit R counter, dual-modulus prescaler (8/9, 16/17, 32/33, 64/65), 3-wire serial interface, and operates from 2.7 V to 5.5 V. It enables precise frequency synthesis in GSM base station transmitters.
For engineers reviewing the ADF4110BRU-REEL7 datasheet, ADF4110BRU-REEL7 pinout, ADF4110BRU-REEL7 application, or ADF4110BRU-REEL7 equivalent, key selection criteria include its 550 MHz RF input range, programmable charge pump current (625 µA to 5 mA), analog/digital lock detect, separate VP supply for extended tuning voltage, and industrial temperature range (−40°C to +85°C).
Technical Context
The ADF4110BRU-REEL7 implements a digital phase-frequency detector (PFD) with precision charge pump, programmable reference divider (R counter), and dual-modulus prescaler (P/P+1) to realize fractional-N synthesis. Its 6-bit A and 13-bit B counters configure the N-divider value (N = BP + A), supporting fine frequency resolution in closed-loop PLL systems with external VCO and loop filter.
It supports 3-wire serial programming (DATA/CLK/LE), hardware/software power-down modes, and multiplexed MUXOUT for lock detect or scaled RF/reference outputs. The separate VP supply (AVDD ≤ VP ≤ 6.0 V) enables higher tuning voltage headroom in 3 V systems without increasing AVDD/DVDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Input Frequency | 50 MHz to 550 MHz - supports GSM/PCS/DCS bands with −10 dBm sensitivity at 3 V operation. |
| Phase Detector Max Frequency | 55 MHz - sets upper limit on PFD comparison rate, directly constraining loop bandwidth and settling time. |
| Charge Pump Current Range | 625 µA to 5 mA - programmable via RSET resistor; determines loop filter gain and VCO tuning slope interaction. |
| Supply Voltage Range | 2.7 V to 5.5 V (AVDD/DVDD); VP ≥ AVDD up to 6.0 V - enables 3 V system compatibility with 6 V VCO tuning range. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade wireless infrastructure and handheld equipment environments. |
| Power Consumption | 5.5 mA max (typ. 4.5 mA at 3 V) - low quiescent current supports battery-sensitive or thermally constrained designs. |
| Reference Input Range | 5 MHz to 104 MHz - allows flexible crystal oscillator or clock source selection for PFD input. |
Pinout & Package
TSSOP-16 package with exposed paddle (connected to AGND). Pin count and layout match JEDEC MO-153 standard; RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RSET | Charge pump current setting | Resistor to CPGND sets ICPmax (e.g., 4.7 kΩ → 5 mA); nominal voltage 0.56 V. |
| CP | Charge pump output | Drives external loop filter; ±ICP current sourced/sunk based on PFD error signal. |
| CPGND | Charge pump ground return | Dedicated low-noise ground path for CP; must be isolated from DGND/AGND except at single point. |
| RFINA / RFINB | RF prescaler differential input | AC-coupled small-signal inputs; RFINA accepts VCO output; RFINB is complementary for noise rejection. |
| REFIN | Reference clock input | CMOS input (threshold ≈ DVDD/2); accepts TTL/CMOS oscillators or AC-coupled sources (5–104 MHz). |
| CE | Chip enable | Active-low control: logic low powers down device and places CP in high-impedance state. |
| DATA / CLK / LE | 3-wire serial interface | 24-bit shift register loaded MSB-first; LE latches data into selected register (A/B/R/Function latch). |
| MUXOUT | Multiplexer output | Selectable output: lock detect status, divided RF, or divided REFIN - aids real-time PLL monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-modulus prescaler | Configurable 8/9, 16/17, 32/33, or 64/65 division - enables wide N-divider range while maintaining high PFD frequency. |
| Separate VP supply | VP ≥ AVDD up to 6.0 V - extends VCO tuning voltage beyond core supply, critical for wide-range varactor-based VCOs. |
| Programmable antibacklash pulse width | Adjustable to suppress false lock detection during fast frequency transitions - improves transient stability. |
| Analog and digital lock detect | Dual lock indicators - analog LD reflects PFD phase alignment; digital LD provides CMOS-compatible status flag. |
| Hardware/software power-down | CE pin or F2 bit control - reduces IDD to 1 µA typical, enabling rapid wake-up in burst-mode communication systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF PLL synthesizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADF4111BRU-REEL7 | Higher RF input range (0.08–1.2 GHz) and 1.2 GHz max prescaler output; identical pinout and interface. | Supports PCS/DCS/WCDMA bands beyond ADF4110BRU-REEL7's 550 MHz limit; same industrial temp grade. | Choose when extending to 1 GHz+ VCO frequencies without changing PCB layout or firmware interface. |
| LMX2485EVMX/NOPB | Wider RF range (300 MHz–3.8 GHz), integrated VCO, SPI interface, and lower phase noise (−95 dBc/Hz @ 1 kHz). | Reduces external component count but requires different loop filter design and SPI driver integration. | Prefer for new designs targeting higher integration and broader frequency coverage, accepting SPI migration effort. |
Compared with ADF4110BRU-REEL7, ADF4111BRU-REEL7 offers direct pin-compatible extension to 1.2 GHz, while LMX2485EVMX/NOPB trades external VCO dependency for higher integration and wider bandwidth-making it suitable for compact, multi-band systems where layout space and BOM count are critical.

FAQ
What is the maximum RF input frequency supported by the ADF4110BRU-REEL7?
The ADF4110BRU-REEL7 supports an RF input frequency range of 50 MHz to 550 MHz at 3 V operation, with −10 dBm sensitivity. This makes it suitable for GSM 900 MHz band (after prescaling) and other sub-600 MHz wireless standards. Operation below 50 MHz requires slew rate >30 V/µs to ensure reliable prescaler triggering.
Does the ADF4110BRU-REEL7 require an external loop filter?
Yes, the ADF4110BRU-REEL7 requires an external passive loop filter between the CP pin and the VCO tuning input. The charge pump delivers programmable ±ICP current (625 µA–5 mA), and the filter's transfer function determines PLL stability, lock time, and phase noise performance. No internal filtering is provided.
Can the ADF4110BRU-REEL7 operate with a 3 V supply and still drive a 5 V-tuned VCO?
Yes. The ADF4110BRU-REEL7 features a separate VP supply pin that can be set to up to 6.0 V, independent of the 2.7–5.5 V AVDD/DVDD rails. With AVDD = DVDD = 3 V and VP = 5 V or 6 V, the charge pump delivers full tuning voltage range to the VCO while maintaining low core power consumption.
How does the dual-modulus prescaler enhance frequency resolution in the ADF4110BRU-REEL7?
The ADF4110BRU-REEL7 uses a dual-modulus prescaler (e.g., 8/9) in conjunction with 6-bit A and 13-bit B counters to implement N = BP + A. This allows fine frequency steps without reducing PFD frequency - preserving loop bandwidth and phase noise - unlike simple fixed-divide architectures limited by reference frequency granularity.
Is the ADF4110BRU-REEL7 pin-compatible with other devices in the ADF411x family?
Yes, the ADF4110BRU-REEL7 shares identical TSSOP-16 pinout and register map with ADF4111BRU-REEL7, ADF4112BRU-REEL7, and ADF4113BRU-REEL7. This enables drop-in replacement across the family when scaling RF range (550 MHz → 4.0 GHz), provided the prescaler and loop filter are re-optimized for the target VCO frequency.
