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 AD9522-51 provides a multioutput clock distribution function with subpicosecond jitter performance, along with an on-chip PLL that can be used with an external VCO.   The AD9522 serial interface supports both SPI and I2C® ports. An in-package EEPROM can be programmed through the serial interface and store user-defined register settings for power-up and chip reset.The AD9522 features 12 LVDS outputs in four groups. Any of the 800 MHz LVDS outputs can be reconfigured as two 250 MHz CMOS outputs.Each group of outputs has a divider that allows both the divide ratio (from 1 to 32) and the phase (coarse delay) to be set.The AD9522 is available in a 64-lead LFCSP and can be operated from a single 3.3 V supply. The external VCO can have an operating voltage up to 5.5 V.The AD9522 is specified for operation over the standard industrial range of −40°C to +85°C.The AD9520-5 is an equivalent part to the AD9522-5 featuring LVPECL/CMOS drivers instead of LVDS/CMOS drivers.1The AD9522 is used throughout this data sheet to refer to all the members of the AD9522 family. However, when AD9522-5 is used, it is referring to that specific member of the AD9522 family.ApplicationsLow jitter, low phase noise clock distributionClock generation and translation for SONET, 10Ge, 10G FC, and other 10 Gbps protocolsForward error correction (G.710)Clocking high speed ADCs, DACs, DDSs, DDCs, DUCs, MxFEsHigh performance wireless transceiversATE and high performance instrumentationBroadband infrastructures

The ADCLK854 is a 1.2 GHz/250 MHz LVDS/CMOS fanout buffer optimized for low jitter and low power operation. Possible configurations range from 12 LVDS to 24 CMOS outputs, including combinations of LVDS and CMOS outputs. Three control lines are used to determine whether fixed blocks of outputs (three banks of four) are LVDS or CMOS outputs.The ADCLK854 offers two selectable inputs and a sleep mode feature. The IN_SEL pin state determines which input is fanned out to all the outputs. The SLEEP pin enables a sleep mode to power down the device.The inputs accept various types of single-ended and differential logic levels including LVPECL, LVDS, HSTL, CML, and CMOS. Table 8 provides interface options for each type of connection.This device is available in a 48-pin LFCSP package. It is specified for operation over the standard industrial temperature range of −40°C to +85°C.APPLICATIONSLow jitter clock distributionClock and data signal restorationLevel translationWireless communicationsWired communicationsMedical and industrial imagingATE and high performance instrumentation

The ADCLK948 is an ultrafast clock fanout buffer fabricated on the Analog Devices, Inc., proprietary XFCB3 silicon germanium (SiGe) bipolar process. This device is designed for high speed applications requiring low jitter.The device has two selectable differential inputs via the IN_SEL control pin. Both inputs are equipped with center tapped, differential, 100 Ω on-chip termination resistors. The inputs accept dc-coupled LVPECL, CML, 3.3 V CMOS (single-ended), and ac-coupled 1.8 V CMOS, LVDS, and LVPECL inputs. A VREFx pin is available for biasing ac-coupled inputs. The ADCLK948 features eight full-swing emitter coupled logic(ECL) output drivers. For LVPECL (positive ECL) operation, bias VCC to the positive supply and VEE to ground. For ECL operation, bias VCC to ground and VEE to the negative supply.The output stages are designed to directly drive 800 mV eachside into 50 Ω terminated to VCC -2V for a total differential output swing of 1.6V. The ADCLK948 is available in a 32-lead LFCSP and specified for operation over the standard industrial temperature range of −40°C to +85°C.APPLICATIONS Low jitter clock distribution Clock and data signal restoration Level translation Wireless communications Wired communications Medical and industrial imaging ATE and high performance instrumentation

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 HMC582LP5(E) is a GaAs InGaP Herterojunction Bipolar Transistor (HBT) MMIC VCOs. The HMC582LP5(E) integrates resonators, negative resistance devices, varactor diodes and feature half frequency and divide-by-4 outputs. The VCO's phase noise performance is excellent over temperature, shock and process due to the oscillator's monolithic structure.Power output is +9 dBm typical from a +5V supply voltage. The prescaler and RF/2 functions can be disabled to conserve current if not required. The voltage controlled oscillator is packaged in a leadless QFN 5×5 mm surface mount package, and requires no external matching components.APPLICATIONS Point-to-Point Radios Point-to-Multi-Point Radios Test Equipment & Industrial Controls SATCOM Military End-Use
