Product details
Overview
ADF4193WCCPZ-RL7 from Analog Devices is a fast-settling, low-phase-noise fractional-N PLL frequency synthesizer designed for GSM/EDGE base station local oscillators. It delivers 5 µs frequency hop across the GSM band with phase settled by 20 µs, 0.5° rms phase error at 2 GHz RF output, and −216 dBc/Hz phase noise figure of merit. Its architecture replaces ping-pong synthesizers in wireless transceiver up/downconversion.
For engineers reviewing the ADF4193WCCPZ-RL7 datasheet, ADF4193WCCPZ-RL7 pinout, ADF4193WCCPZ-RL7 application, or ADF4193WCCPZ-RL7 equivalent, key selection criteria include fast lock timing under GSM time slot constraints, differential charge pump compliance (VP1/VP2 = 5 V), RSET-programmable ICP (104 µA typ), RF input range up to 3.5 GHz, and automotive-grade temperature operation (−40°C to +105°C).
Technical Context
The ADF4193WCCPZ-RL7 implements a Σ-Δ-based fractional interpolator with programmable modulus division, enabling precise frequency synthesis with integer boundary spur suppression. Its dual-loop bandwidth strategy-wide-bandwidth fast lock (via increased ICP and SW1/SW2/SW3 switch control) followed by narrow-bandwidth steady-state operation-meets GSM guard period timing.
It integrates a precision differential charge pump, low-noise differential amplifier (VP3 = 5.0–5.65 V), on-chip 4-bit R counter with optional ×2 doubler, and 24-bit serial interface. The differential CPOUT+/CPOUT− outputs drive external loop filters, while AOUT provides single-ended VCO tuning voltage via internal amplification.

| Charge Pump Current (ICP) | 104 µA typical (RSET = 2.4 kΩ): sets loop filter gain and transient response; adjustable via external resistor. |
| Operating Temperature | −40°C to +105°C (W Version): qualified for automotive base station infrastructure and industrial environments. |
| Reference Input Range | 10–300 MHz: supports crystal oscillators, TCXOs, or divided-down system clocks with REFIN/2 option. |
Pinout & Package
The ADF4193WCCPZ-RL7 is housed in a 32-lead LFCSP (5 mm × 5 mm, 0.5 mm pitch) with exposed thermal pad requiring connection to AGND. Pin functions are validated per Analog Devices Rev. G datasheet Figure 3 and Table 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RFIN+, RFIN− | Differential RF input to prescaler | Accepts ac-coupled 0.4–3.5 GHz signal; requires 100 pF bypass to AGND for impedance matching. |
| CPOUT+, CPOUT− | Differential charge pump outputs | Drive external loop filter; require direct connection to AIN+ and AIN− of integrated differential amplifier. |
| AOUT | Single-ended VCO tuning voltage output | Amplified, buffered VTUNE (1.4 V to VP3−0.3 V); drives external VCO with 7 nV/√Hz output noise. |
| REFIN | CMOS-compatible reference clock input | Accepts 10–300 MHz square wave; threshold at VDD/2; supports dc- or ac-coupling with 100 kΩ input resistance. |
| CLK, DATA, LE | 3-wire serial programming interface | 24-bit shift register control; timing-critical (t1–t7 ≤ 15 ns); supports daisy-chain configuration. |
| RSET | Charge pump current setting node | Resistor-to-ground sets ICP via ICP = 0.25/RSET; nominal 2.4 kΩ yields 104 µA. |
| VP1, VP2, VP3 | Analog power supplies | VP1/VP2 = 4.5–5.5 V (PFD/charge pump); VP3 = 5.0–5.65 V (differential amplifier); each requires dedicated decoupling. |
| MUXOUT | Multiplexed diagnostic output | Selectable lock detect, scaled RF, or scaled reference; enables real-time PLL status monitoring without additional probes. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar fractional-N PLL synthesizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADF4153AACPZ-R7 | Lower max RF input (2.5 GHz), no differential amplifier, −222 dBc/Hz FoM, non-automotive grade (−40°C to +85°C). | Targeted at cost-sensitive test equipment-not qualified for automotive or base station deployment. | Choose when RF range ≤2.5 GHz suffices and VP3-powered differential amplification is unnecessary. |
| LMS8001TR | Integrated transceiver (not standalone synthesizer), includes ADC/DAC, 3.8 GHz max RF, no RSET-adjustable ICP, −210 dBc/Hz FoM. | Used in SDR platforms requiring full radio front-end-not suitable as drop-in LO replacement. | Choose only when system-level integration (not discrete LO synthesis) is the design goal. |
Compared with ADF4153AACPZ-R7 and LMS8001TR, the ADF4193WCCPZ-RL7 uniquely combines automotive qualification, 3.5 GHz RF input, on-chip differential amplifier, and GSM-optimized fast-lock switching-making it the sole choice for hardened base station LO designs requiring guaranteed phase settle within 20 µs.

FAQ
What is the maximum RF input frequency supported by the ADF4193WCCPZ-RL7?
The ADF4193WCCPZ-RL7 supports an RF input frequency range of 0.4 GHz to 3.5 GHz, as specified in the Rev. G datasheet Table 1. This covers all major cellular bands including GSM900, DCS1800, PCS1900, and PHS1900. Operation above 3.5 GHz is not supported-the prescaler architecture limits maximum input to ensure proper division and phase detector compatibility.
How does the ADF4193WCCPZ-RL7 achieve 5 µs frequency hop time?
The ADF4193WCCPZ-RL7 achieves 5 µs frequency hop time through its fast-lock architecture: increasing charge pump current (ICP) during frequency transition, activating on-chip switches (SW1/SW2/SW3) to temporarily modify loop filter dynamics, and using wide-loop-bandwidth mode. The ADF4193WCCPZ-RL7 exits wide-bandwidth mode once frequency lock is detected, then narrows bandwidth for optimal phase noise performance.
What is the function of the RSET pin on the ADF4193WCCPZ-RL7?
The RSET pin on the ADF4193WCCPZ-RL7 sets the charge pump output current (ICP) via an external resistor to ground. Per datasheet Equation ICP = 0.25/RSET, a 2.4 kΩ resistor yields 104 µA typical ICP. This directly controls loop filter gain, lock time, and reference spur magnitude-making RSET a critical design element for optimizing PLL transient and steady-state behavior.
Is the ADF4193WCCPZ-RL7 pin-compatible with earlier ADF4193 variants?
Yes, the ADF4193WCCPZ-RL7 shares identical pinout, package (32-lead LFCSP), and electrical interface with all ADF4193 versions (B, C, W). The "W" suffix denotes automotive qualification (−40°C to +105°C), but mechanical and functional compatibility is maintained across the family-enabling drop-in replacement where extended temperature range is required.
Does the ADF4193WCCPZ-RL7 include an integrated VCO?
No, the ADF4193WCCPZ-RL7 does not include an integrated VCO. It is a PLL synthesizer core that requires an external voltage-controlled oscillator. The device provides differential charge pump outputs (CPOUT+/CPOUT−) and a buffered single-ended tuning voltage (AOUT) to drive the VCO's tuning port-supporting wideband VCOs such as the Sirenza 1843T referenced in the datasheet.
