Product details
Overview
ADF4107BCPZ-REEL from Analog Devices is a 7 GHz PLL frequency synthesizer IC used as a local oscillator in RF up/downconversion stages of wireless transceivers. It features dual-modulus prescaling (8/9, 16/17, 32/33, 64/65), programmable charge pump current (625 µA–5 mA), 2.7–3.3 V supply, and separate VP pin enabling 5 V tuning voltage for wide-range VCOs. It supports broadband wireless access and satellite systems requiring precise, low-noise frequency synthesis.
For engineers reviewing the ADF4107BCPZ-REEL datasheet, ADF4107BCPZ-REEL pinout, ADF4107BCPZ-REEL application, or ADF4107BCPZ-REEL equivalent, key selection criteria include RF input bandwidth (1–7 GHz), PFD frequency limit (104 MHz max), charge pump leakage (<1 nA), lock detect options (analog/digital), and LFCSP-20 package compatibility with high-frequency PCB layout constraints.
Technical Context
The ADF4107BCPZ-REEL implements a digital phase frequency detector (PFD) with programmable antibacklash pulse width (1.3–6.0 ns), precision charge pump with dual current settings, and a 14-bit R counter plus 19-bit N divider (6-bit A + 13-bit B counters). Its dual-modulus prescaler operates at CML levels and feeds CMOS counters limited to ≤300 MHz output.
It requires an external loop filter and VCO to form a complete PLL; the separate VP supply (≥AVDD, up to 5.5 V) extends tuning voltage range without increasing core supply, directly supporting wide-tuning VCOs in 3 V systems. The 3-wire serial interface enables latch-selectable programming of reference, N, function, and initialization registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Input Frequency | 1.0–7.0 GHz: Supports direct synthesis up to Ka-band without frequency doublers. |
| PFD Max Frequency | 104 MHz: Enables high reference frequencies for fine channel spacing and fast lock times. |
| Charge Pump Current | 625 µA–5 mA (programmable): Allows optimization of loop filter bandwidth and phase noise trade-offs. |
| Prescaler Options | 8/9, 16/17, 32/33, 64/65: Ensures contiguous output coverage across wide bands via flexible N-divider design. |
| Supply Voltage Range | 2.7–3.3 V (AVDD/DVDD), VP = AVDD to 5.5 V: Enables 5 V VCO tuning while maintaining 3 V logic compatibility. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PLL frequency synthesizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADF4153AACPZ-R7 | Higher max RF input (6.5 GHz vs. 7.0 GHz), integrated LDO, lower phase noise floor (−225 dBc/Hz), but no separate VP pin. | Better suited for compact, single-supply 5G small cells where board space limits discrete LDO use; lacks VP flexibility for wide-tuning VCOs. | Select ADF4153A when integrated power management and lowest phase noise are prioritized over VCO tuning voltage headroom. |
| HMC703LP4E | Wider RF range (up to 13 GHz), higher PFD frequency (200 MHz), but requires 5 V AVDD/DVDD and has no analog lock detect. | Targeted at millimeter-wave radar and E-band links; incompatible with 3 V systems and lacks analog lock monitoring for lab instrumentation. | Choose HMC703LP4E only for >10 GHz applications where 3 V operation and analog lock feedback are not required. |
Compared with ADF4107BCPZ-REEL, ADF4153A offers superior noise and integration but sacrifices VP-based VCO tuning flexibility, while HMC703LP4E extends frequency range at the cost of 3 V compatibility and diagnostic capability-making ADF4107BCPZ-REEL optimal for 3–7 GHz infrastructure with wide-tuning VCOs.

FAQ
What is the maximum RF input frequency supported by the ADF4107BCPZ-REEL?
The ADF4107BCPZ-REEL supports an RF input frequency range of 1.0 GHz to 7.0 GHz, as specified in the Rev. D datasheet under "RF Input Frequency (RFIN)" with min/max values of 1.0/7.0 GHz. This enables direct synthesis in Ka-band applications without requiring frequency multipliers.
Does the ADF4107BCPZ-REEL require an external loop filter?
Yes, the ADF4107BCPZ-REEL requires an external passive loop filter connected between the CP pin and the tuning port of an external VCO. The IC itself contains only the PFD, charge pump, and dividers; the loop filter determines PLL bandwidth, stability, and transient response.
Can the ADF4107BCPZ-REEL operate from a single 3.3 V supply?
Yes, the ADF4107BCPZ-REEL operates with AVDD and DVDD at 2.7–3.3 V. However, the VP pin must be ≥AVDD (e.g., 3.3–5.5 V) to support extended VCO tuning voltage. Using VP = 5 V with AVDD = 3.3 V is standard practice for wide-range VCOs.
How is lock detection implemented on the ADF4107BCPZ-REEL?
The ADF4107BCPZ-REEL provides both digital and analog lock detect outputs via the MUXOUT pin. Digital lock detect asserts high after 3 or 5 consecutive PFD cycles with phase error <15 ns (configurable via LDP bit); analog lock detect outputs narrow low-going pulses when locked, requiring a 10 kΩ pull-up resistor.
What package type is used for the ADF4107BCPZ-REEL?
The ADF4107BCPZ-REEL uses a 20-lead LFCSP (Lead Frame Chip Scale Package), 4 mm × 4 mm, 0.5 mm pitch, with an exposed thermal pad that must be soldered to AGND for thermal and electrical performance per datasheet Figure 4 and Table 4.
