Analog Devices Inc. ADF4113HVBRUZ-RL7

Overview

ADF4113HVBRUZ-RL7 from Analog Devices is a high-voltage integer-N PLL frequency synthesizer with 15 V charge pump output, 200 MHz–4.0 GHz RF input range, and dual-modulus prescaler (8/9, 16/17, 32/33, 64/65). It drives high-tuning-voltage VCOs directly using passive loop filters in IF/RF local oscillator generation for wireless base stations and point-to-point radios.

For engineers reviewing the ADF4113HVBRUZ-RL7 datasheet, ADF4113HVBRUZ-RL7 pinout, ADF4113HVBRUZ-RL7 application, or ADF4113HVBRUZ-RL7 equivalent, key selection criteria include charge pump voltage compliance (13.5–16.5 V), programmable ICP (80 µA / 640 µA), digital lock detect precision (3 ns or 10 ns), and TSSOP-16 package compatibility with ADF4110/ADF4111/ADF4112/ADF4113 family designs.

Technical Context

The ADF4113HVBRUZ-RL7 integrates a low-noise phase frequency detector (PFD), precision high-voltage charge pump, 14-bit R counter, 13-bit B/6-bit A counters, and dual-modulus prescaler (P/P+1) to realize N = BP + A division. Its PFD includes programmable antibacklash pulse width (7.2 ns only) to eliminate dead zone and minimize reference spurs.

It supports 3-wire serial interface (CLK/DATA/LE) with 24-bit shift register, latch-select control bits (C2/C1), and MUXOUT multiplexer for accessing internal signals including digital lock detect, N/R divider outputs, or analog lock detect. Power-down is controlled via CE pin or software bit F2 in function latch.

FAQ

What is the maximum RF input frequency supported by the ADF4113HVBRUZ-RL7?

The ADF4113HVBRUZ-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; at 3 V, the maximum is 3.7 GHz. The prescaler output must remain ≤200 MHz, so prescaler selection (e.g., 16/17 for 2 GHz input) is required to meet this constraint. This specification is verified in Table 1 of the Rev. B datasheet.

Does the ADF4113HVBRUZ-RL7 require an external active loop filter?

No, the ADF4113HVBRUZ-RL7 does not require an external active loop filter. Its 15 V charge pump (VP = 13.5–16.5 V) enables direct drive of high-tuning-voltage VCOs using passive loop filters-reducing component count, power consumption, and noise contribution. This capability is explicitly stated in the General Description and validated in application circuits using Sirenza VCO190-1500T(Y) on EV-ADF4113HVSDZ1 evaluation board.

How is the charge pump current configured on the ADF4113HVBRUZ-RL7?

The ADF4113HVBRUZ-RL7 charge pump current is configured via the CPI3:CPI1 bits in the function latch (Figure 22). Two settings are available: 80 µA (CPI3:CPI1 = 000) and 640 µA (CPI3:CPI1 = 111), with nominal accuracy of ±2.5%. The RSET pin connects to CPGND through a resistor (e.g., 4.7 kΩ) to set ICPmax = 3/RSET, as defined in Table 5 and Figure 13.

Is the ADF4113HVBRUZ-RL7 pin-compatible with other ADF411x devices?

Yes, the ADF4113HVBRUZ-RL7 is pin-compatible with ADF4110, ADF4111, ADF4112, ADF4113, ADF4106, and ADF4002 synthesizers in TSSOP-16 package. Pin functions-including RSET, CP, CPGND, RFINA/B, REFIN, CE, CLK, DATA, LE, MUXOUT, and VP-are identical. This allows direct substitution in existing layouts, though VP voltage requirements (13.5–16.5 V) must be verified in the target design.

What is the purpose of the MUXOUT pin on the ADF4113HVBRUZ-RL7?

The MUXOUT pin on the ADF4113HVBRUZ-RL7 provides access to internal signals via a 3-bit control (M3:M1). Configurable outputs include digital lock detect (active high), analog lock detect (open-drain), N-divider output, R-divider output, SDOUT, DVDD, or DGND. This enables real-time lock monitoring, loop diagnostics, and system synchronization without additional probing-functionality confirmed in Figure 18 and Table 5 of the datasheet.
