The ADF41020 frequency synthesizer can be used to implement local oscillators as high as 18 GHz in the up conversion and down conversion sections of wireless receivers and transmitters. It consists of a low noise, digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and high frequency programmable feedback dividers (A, B, and P). A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). The synthesizer can be used to drive external microwave VCOs via an active loop filter. Its very high bandwidth means a frequency doubler stage can be eliminated, simplifying system architecture and reducing cost. The ADF41020 is software-compatible with the existing ADF4106/ADF4107/ADF4108 family of devices from Analog Devices, Inc. Their pinouts match very closely with the exception of the ADF41020’s single-ended RF input pin, meaning only a minor layout change is required when updating current designs.Applications Microwave point-to-point/multipoint radios Wireless infrastructure VSAT radios Test equipment Instrumentation

The AD9837 is a low power, programmable waveform generatorcapable of producing sine, triangular, and square wave outputs.Waveform generation is required in various types of sensing,actuation, and time domain reflectometry (TDR) applications. The outputfrequency and phase are software programmable, allowing easytuning. The frequency registers are 28 bits: with a 16 MHz clock rate, resolution of 0.06 Hz can be achieved; with a 5 MHz clock rate, the AD9837can be tuned to 0.02 Hz resolution.The AD9837 is written to via a 3-wire serial interface. This serialinterface operates at clock rates up to 40 MHz and is compatiblewith DSP and microcontroller standards. The device operateswith a power supply from 2.3 V to 5.5 V.The AD9837 has a power-down (SLEEP) function. Sections of the device that are not being used can be powered down to minimize the current consumption of the part. For example, the DAC can be powered down when a clock output is being generated.The AD9837 is available in a 10-lead LFCSP_WD package.APPLICATIONS Frequency stimulus/waveform generation Liquid and gas flow measurement Sensory applications: proximity, motion, and defect detection Line loss/attenuation Test and medical equipment Sweep/clock generators Time domain reflectometry (TDR) applications

The AD9531 provides a multioutput clock generator function and three on-chip phase-locked loop (PLL) cores with SPI programmable output frequencies and formats.PLL1 provides two reference inputs and 10 outputs and includes four user selectable loop configurations. The PLL has a fully integrated loop filter requiring only a single external capacitor (or a series RC network). PLL1 provides a wide range of output frequencies up to 400 MHz and is capable of operating with an external voltage controlled crystal oscillator (VCXO) and loop filter, instead of the integrated voltage controlled oscillator (VCO) and loop filter.PLL2 is an integer-N PLL providing a single reference input and 12 outputs. PLL2 synthesizes output frequencies up to 400 MHz from the REF2_x source and synchronizes the output clocks to the input reference.PLL3 provides a single reference input and two outputs. PLL3 synthesizes output frequencies up to 400 MHz from the REF3_x source and synchronizes the output clocks to input reference.The AD9531 is available in an 88-lead LFCSP and is specified over the −40°C to +85°C operating temperature range.Throughout this data sheet, multifunction pins, such as LOR/M4, are referred to either by the entire pin name or by a single function of the pin (for example, LOR, when only that function is relevant). In other cases, the text and figures of this data sheet contain references to a channel rather than a pin. For example, REF_A refers to the REF_A channel rather than the REF_AP and REF_AN pins. Likewise, OUT3_1 refers to Channel 1 of PLL3 rather than the OUT3_1P and OUT3_1N pins. Additionally, an abbreviated notation for a pin pair replaces an explicit reference to a each pin (for example, REF_Ax signifies the REF_AN and REF_AP pins.).Applications Radio equipment controller clocking Low jitter/phase noise clock generation and distribution Clock generation and translation for SONET, 10GE, 10G FC, and other 10 Gbps protocols 40 Gbps/100 Gbps networking line cards, including SONET, synchronous ethernet, OTU2/3/4 Forward error correction (G.710) High performance wireless transceivers ATE and high performance instrumentation Broadband infrastructures Ethernet line cards, switches, and routers SATA and PCI-express
