EV-ADF5610SD1Z

Analog Devices Inc.
The ADF5610 allows implementation of fractional-N or Integer N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference source. The wideband microwave voltage controlled oscillator (VCO) design permits frequency operation from 7300 MHz to 14600 MHz at a single radio frequency (RF) output. A series of frequency dividers with a differential frequency output allows operation from 57 MHz to 14600 MHz. Analog and digital power supplies for the PLL circuitry range from 3.1 V to 3.5 V, and the VCO supplies are between 4.75 V and 5.25 V. The charge pump supply voltage can be extended up to 3.6 V for improved frequency band overlap and extended upper frequency range.The ADF5610 has an integrated VCO with a fundamental frequency of 3650 MHz to 7300 MHz. These frequencies are internally doubled and routed to the RFOUT pin. An additional differential output allows the doubled VCO frequency to be divided by 1, 2, 4, 8, 16, 32, 64, or 128, allowing the user to generate RF output frequencies as low as 57 MHz. A simple 3?wire serial port interface (SPI) provides control of all on-chip registers. To conserve power, this divider block can be disabled when not needed through the SPI interface. Likewise, the output power for both the single-ended output and the differential output are programmable via the VCO register settings. The ADF5610 also contains various power-down modes for the VCO circuitry and PLL circuitry.The integrated phase detector (PD) and delta-sigma (?-?) modulator, capable of operating at up to 100 MHz, permit wide loop bandwidths and fast frequency tuning with a typical spurious level of ?100 dBc.With phase noise levels from ?115 dBc/Hz at 7.3 GHz to ?109 dBc/Hz at 14.6 GHz, the ADF5610 is equipped to minimize blocker effects, and to improve receiver sensitivity and transmitter spectral purity. The low phase noise floor eliminates any contribution to modulator and mixer noise floor in transmitter applications.The ADF5610 is a PLL with integrated VCO. The device features an innovative programmable performance technology that enables the ADF5610 to tailor current consumption and corresponding noise performance to individual applications by selecting either a low current consumption mode or a high performance mode for improved phase noise performance.Additional features of the ADF5610 include approximately 3 dBof RFOUT gain control in 1.5 dB steps and 5 dB of control onthe differential port in approximately 2.5 dB steps. Finally, the ?-?modulator with exact frequency mode enables users to generateoutput frequencies with 0 Hz frequency error.APPLICATIONSMilitary and defenseTest equipmentClock generationWireless infrastructureSatellite and very small aperture terminal (VSAT)Microwave radio

DC1012A-A

Analog Devices Inc.
The LTC2499 is a 16-channel (eight differential), 24-bit, No Latency ??? ADC with Easy Drive technology and a 2-wire, I2C interface. The patented sampling scheme eliminates dynamic input current errors and the shortcomings of on-chip buffering through automatic cancellation of differential input current. This allows large external source impedances and rail-to-rail input signals to be directly digitized while maintaining exceptional DC accuracy. The LTC2499 includes a high accuracy, temperature sensor and an integrated oscillator. This device can be configured to measure an external signal (from combinations of 16 analog input channels operating in single-ended or differential modes) or its internal temperature sensor. The integrated temperature sensor offers 1/30th?C resolution and 2?C absolute accuracy. The LTC2499 allows a wide common mode input range (0V to VCC), independent of the reference voltage. Any combination of single-ended or differential inputs can be selected and the first conversion, after a new channel is selected, is valid. Access to the multiplexer output enables optional external amplifiers to be shared between all analog inputs and auto calibration continuously removes their associated offset and drift.Applications Direct Sensor Digitizer Direct Temperature Measurement Instrumentation Industrial Process Control
