ADF4368Microwave Wideband Synthesizer with Integrated VCO | Clock/Timing | 2 | Active | The ADF4368 is a high performance, ultra-low jitter, integer-N and fractional-N phase-locked loop (PLL) with integrated VCO ideally suited for frequency conversion applications.The high performance PLL has a figure of merit of −239 dBc/Hz, very low 1/f noise of normalized −287 dBc/Hz and high PFD frequency that can achieve ultra-low in-band noise and integrated jitter. The ADF4368 can generate any frequency from 800 MHz to 12.8 GHz without an internal doubler, which eliminates the need for sub-harmonic filters. The Σ-Δ modulator includes a 25-bit fixed modulus that allows hertz frequency resolution and an additional 17-bit variable modulus, which allows even finer resolution and flexibility for frequency planning. The 9 dBm output power at 12.8 GHz in single-ended configuration with 16 step power adjust feature makes it very useful for any application.For multiple frequency conversion applications, such as phase array radar or massive MIMO systems, the outputs of multiple ADF4368 can be aligned by using the SYNC input or EZSync™. The EZSync method is used when it is difficult to distribute the SYNC signal to all devices precisely. For applications that require deterministic delay or delay adjustment capability, a programmable reference to output delay with <1 ps resolution is provided. The reference to output delay is guaranteed across multiple devices and temperature, allowing for predictable and precise multichip alignment.The simplicity of the ADF4368 block diagram eases development time with a simplified serial-peripheral interface (SPI) register map, external SYNC input, and repeatable multichip phase alignment both in integer mode and fractional mode.APPLICATIONSWireless infrastructure (MC-GSM, 5G)Test and measurementAerospace and defense |

The wideband microwave voltage controlled oscillator (VCO) design allows frequencies from 62.5 MHz to 32 GHz to be generated.The ADF4371 has an integrated VCO with a fundamental output frequency ranging from 4000 MHz to 8000 MHz.

A frequency multiplier at RF16x generates from 8 GHz to 16 GHz. A frequency quadrupler generates frequencies from 16 GHz to 32 GHz at RF32x. RFAUX8x duplicates the frequency range of RF8x or permits direct access to the VCO output. To suppress the unwanted products of frequency multiplication, a harmonic filter exists between the multipliers and the output stages of RF16x and RF32x.Control of all on-chip registers is through a 3-wire interface. The ADF4371 operates with analog and digital power supplies ranging from 3.15 V to 3.45 V, and 5 V for the VCO power supply.
