Analog Devices Inc. ADF4113HVBCPZ-RL7

Overview

ADF4113HVBCPZ-RL7 from Analog Devices is a high-voltage integer-N PLL frequency synthesizer with 15 V charge pump output, 200 MHz to 4.0 GHz RF input range, 2.7–5.5 V digital/analog supply, and dual selectable charge pump currents (80 µA / 640 µA). It directly drives high-tuning-voltage VCOs in wireless base station LO generation.

For engineers reviewing the ADF4113HVBCPZ-RL7 datasheet, ADF4113HVBCPZ-RL7 pinout, ADF4113HVBCPZ-RL7 application, or ADF4113HVBCPZ-RL7 equivalent, this device supports precise local oscillator synthesis for IF/RF up/downconversion, clocking of high-speed ADCs/DACs, and test equipment requiring low-phase-noise, high-voltage loop control.

Technical Context

The ADF4113HVBCPZ-RL7 integrates a low-noise phase frequency detector (PFD), precision 15 V charge pump, 14-bit R counter, 13-bit B/6-bit A counters, and dual-modulus prescaler (8/9, 16/17, 32/33, 64/65) to realize N = BP + A division. Its PFD includes programmable antibacklash pulse (7.2 ns fixed) to eliminate dead zone and minimize reference spurs.

It uses a 3-wire serial interface (CLK/DATA/LE) to configure latches for reference division, feedback division, and function control-including MUXOUT selection, lock detect mode, CP current setting, and power-down activation via CE pin or software bit PD1.

FAQ

What is the maximum RF input frequency supported by the ADF4113HVBCPZ-RL7?

The ADF4113HVBCPZ-RL7 supports an RF input frequency range of 200 MHz to 4.0 GHz. At 5 V supply, the upper limit is confirmed at 4.0 GHz with −5 dBm input level; below 5 MHz, slew rate must exceed 100 V/µs to ensure proper operation. This makes the ADF4113HVBCPZ-RL7 suitable for microwave and cellular band applications including LTE and 5G FR1.

How does the ADF4113HVBCPZ-RL7 achieve 15 V charge pump output with a 5.5 V supply?

The ADF4113HVBCPZ-RL7 uses an internal charge pump circuit powered by the dedicated VP pin (13.5–16.5 V), which is separate from the 2.7–5.5 V AVDD/DVDD rails. The CP pin outputs ±ICP current referenced to VP, enabling direct 15 V tuning voltage generation into passive loop filters-no external op-amp required. This architecture is explicitly designed into the ADF4113HVBCPZ-RL7 die.

Can the ADF4113HVBCPZ-RL7 replace the ADF4113BCPZ-RL7 without PCB changes?

No-ADF4113HVBCPZ-RL7 requires a 13.5–16.5 V VP supply rail and updated decoupling on VP, plus revised loop filter component ratings to handle 15 V. While pinout and logic interface are identical, the high-voltage domain necessitates layout review. The ADF4113HVBCPZ-RL7 is not a drop-in replacement unless the PCB accommodates the VP rail and HV-safe routing.

What are the two charge pump current options for the ADF4113HVBCPZ-RL7 and how are they selected?

The ADF4113HVBCPZ-RL7 offers 80 µA (low) and 640 µA (high) charge pump current settings, selected via CPI3/CPI2/CPI1 bits in the function latch (per Figure 22). With RSET = 4.7 kΩ, the high setting yields 640 µA; the low setting reduces ICP proportionally. This selection directly impacts loop bandwidth, phase margin, and in-band phase noise-critical for matching VCO gain (K_vco) and filter design.

Does the ADF4113HVBCPZ-RL7 support both analog and digital lock detect outputs?

Yes-the ADF4113HVBCPZ-RL7 provides both analog and digital lock detect via the MUXOUT pin, configured using M3/M2/M1 bits. Digital lock detect is active-high with programmable precision (3 ns or 10 ns phase error window); analog lock detect is open-drain N-channel output requiring a 10 kΩ pull-up, producing narrow pulses when locked. Both are accessible simultaneously only through time-multiplexed MUXOUT selection.
