The ADF4159 is a 13 GHz, fractional-N frequency synthesizer with modulation and both fast and slow waveform generation capability. The part uses a 25-bit fixed modulus, allowing subhertz frequency resolution.The ADF4159 consists of a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. The ?-?-based fractional interpolator allows programmable fractional-N division. The INT and FRAC registers define an overall N divider as N = INT + (FRAC/225).The ADF4159 can be used to implement frequency shift keying (FSK) and phase shift keying (PSK) modulation. Frequency sweep modes are also available to generate various waveforms in the frequency domain, for example, sawtooth and triangular waveforms. Sweeps can be set to run automatically, or each step manually triggered by an external pulse. The ADF4159 features cycle slip reduction circuitry, which enables faster lock times without the need for modifications to the loop filter.Control of all on-chip registers is via a simple 3-wire interface. The ADF4159 operates with an analog power supply in the range of 2.7 V to 3.45 V and a digital power supply in the range of 1.62 V to 1.98 V. The device can be powered down when not in use.ApplicationsCommunications infrastructureCommunications test equipmentInstrumentationFMCW radars

The ADF4401A is a fully integrated, system in package (SiP) translation loop (also known as an offset loop) module that includes a voltage controlled oscillator (VCO) and calibration phase-locked loop (PLL) circuit. Designed for highly jitter sensitive applications, this solution reduces board space and complexity compared to traditional discrete translation loop solutions designed on a printed circuit board (PCB). The time to market is significantly reduced by taking advantage of this highly integrated solution with in package circuitry and enhanced isolation that attenuates spurious components. The ADF4401A provides a frequency synthesis solution for engineers designing highly competitive systems. The ADF4401A requires an external phase detector or phase frequency detector (PFD) and an external local oscillator (LO) to form a frequency synthesis solution. The ADF4401A implements an integrated downconversion mixing stage in the feedback loop that sets the loop gain to 1 and minimizes the in band phase noise. By combining the frequency downconversion stage and low noise, integrated, wideband, VCO technology from Analog Devices, Inc., the ADF4401A offers a wideband jitter performance of 9 fs rms at 8 GHz output. The output jitter performance is largely dependent on the performance of the external offset LO. The ADF4401A module uses an internal PFD and VCO calibration circuitry to select the appropriate VCO band. The user can disable the calibration circuitry and close the loop using the external PFD. All on-chip registers are controlled via a serial port interface (SPI). APPLICATIONSInstrumentation and measurement Automated test equipment Aerospace and defense

The ADGS1414D contains eight independent SPST switches. A serial peripheral interface (SPI) controls the switches. The SPI has robust error detection features, such as cyclic redundancy check (CRC) error detection, invalid read and write address detection, and SCLK count error detection. It is possible to daisy-chain multiple ADGS1414D devices together. Daisy-chain mode enables the configuration of multiple devices with a minimal amount of digital lines. The route of digital signals and supplies through the ADGS1414D allows for a further increase in channel density. Integrated passive components eliminate the need for external passive components. FUNCTIONAL BLOCK DIAGRAM Figure 1. The ADGS1414D is suited to high density switching applications, such as large switching matrices and fanout applications. Each switch conducts equally well in both directions when on, and each switch has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. Multifunction pin names may be referenced by their relevant function only.Applications?

The voltage at the IDAC output pins can also be measured by the ADC, which is useful for controlling the power consumption of the current DACs. Additionally, chip temperature and supply voltages can be measured.The ADC input voltage is 0 V to VREF. A sequencer is provided, which allows a user to select a set of ADC channels to be measured in sequence without software involvement during the sequence. The sequence can optionally repeat automatically at a user selectable rate.Up to eight VDACs are provided with output ranges that are programmable to one of two voltage ranges.Four IDAC sources are provided. The output currents are programmable with ranges of 0 mA to 150 mA. A low drift band gap reference and voltage comparator completes the analog input peripheral set.The ADuCM320 can be configured so that the digital and analog outputs will retain their output voltages and currents through a watchdog or software reset sequence.

Also integrated on chip are 2 ? 128 kB Flash/EE memory and 32 kB of SRAM. The flash comprises two separate 128 kB blocks supporting execution from one flash block and simultaneous writing/erasing of the other flash block.The ADuCM320 operates from an on-chip oscillator or a 16 MHz external crystal and a PLL at 80 MHz. This clock can optionally be divided down to reduce current consumption. Additional low power modes can be set via software. In normal operating mode, the ADuCM320 digital core consumes about 300 ?A per MHz.The device includes an MDIO interface capable of operating at up to 4 MHz. The capability to simultaneously execute from one flash block and write/erase the other flash block makes the ADuCM320 ideal for 10G, 40G, and 100G optical applications. User programming is eased by incorporating PHYADR and DEVADD hardware comparators. In addition, the nonerasable kernel code plus flags in user flash provide assistance by allowing user code to robustly switch between the two blocks of user flash code and data spaces.The ADuCM320 integrates a range of on-chip peripherals that can be configured under software control, as required in the appli-cation. These peripherals include 1 ? UART, 2 ? I2C, and 2 ?

A 16-bit PWM with seven output channels is also provided.GPIO pins on the device power up in high impedance input mode. In output mode, the software chooses between open-drain mode and push-pull mode. The pull-up resistors can be disabled and enabled in software. In GPIO output mode, the inputs can remain enabled to monitor the pins. The GPIO pins can also be programmed to handle digital or analog peripheral signals, in which case the pin characteristics are matched to the specific requirement.A large support ecosystem is available for the ARM Cortex-M3 processor to ease product development of the ADuCM320.
