The LTC2956 is a micropower, wide input voltage range, configurable wake-up timer with pushbutton control. It periodically wakes up and turns on a connected system to perform tasks like monitoring temperature or capturing images. After completing the task, the LTC2956 turns the system off to conserve power.The wake-up timer period can be adjusted from 250ms to 39 days using configuration resistors. The system awake time can be controlled by the input pulse at the SLEEP pin or adjusted by the capacitor at the ONMAX pin. The LTC2956 operates over a wide supply input range from 1.5V to 36V. The low 800nA quiescent current suits battery powered applications.The pushbutton input allows the user to shutdown, turn on or reset the wake-up timer. With the timer in shutdown, the quiescent current drops to 300nA. The LTC2956 also provides three status outputs to indicate mode transitions and pushbutton events. Two versions are available for applications requiring either positive or negative enable polarities.Applications Heartbeat Timers Periodic Wake-Up Control Portable and Battery-Powered Equipment Intervalometers Data Acquisition

The AD9559 is a low loop bandwidth clock multiplier that provides jitter cleanup and synchronization for many systems, including synchronous optical networks (SONET/SDH). The AD9559 generates an output clock synchronized to up to four external input references. The digital PLL allows for reduction of input time jitter or phase noise associated with the external references. The digitally controlled loop and holdover circuitry of the AD9559 continuously generates a low jitter output clock even when all reference inputs have failed.The AD9559 operates over an industrial temperature range of −40°C to +85°C. If a single DPLL version of this part is needed, refer to the AD9557.APPLICATIONS Network synchronization, including Synchronous Ethernet and OTN mapping/de-mapping Cleanup of reference clock jitter SONET/SDH clocks up to OC-192, including FEC Stratum 3 holdover, jitter cleanup, and phase transient control Wireless base station controllers Cable infrastructure Data communications

The ADF4152HV is a 5.0 GHz, fractional-N or integer N frequency synthesizer with an integrated high voltage charge pump. The synthesizer can drive external wideband voltage controlled oscillators (VCOs) directly, eliminating the need for operational amplifiers to achieve higher tuning voltages. The integrated high voltage charge pump simplifies design and reduces cost while improving phase noise, in contrast to active filter topologies, which tend to degrade phase noise compared to passive filter topologies.The VCO frequency can be divided by 1, 2, 4, 8, or 16 to allow the user to generate RF output frequencies as low as 31.25 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin and software controllable.A simple 3-wire interface controls all on-chip registers. The charge pump operates from a power supply ranging from 6.0 V to 30 V, whereas the rest of the device operates from 3.0 V to 3.6 V. The ADF4152HV can be powered down when not in use.Applications Wireless infrastructure Microwave point to point/point to multipoint radios Very small aperture terminal (VSAT) radios Test equipment Private land mobile radios

The AD-SYNCHRONA14-EBZ is an ideal self-contained device to use in evaluation and prototyping of applications that need a highly accurate frequency and phase-controlled source clock. It is designed around the Analog Devices AD9545 and HMC7044 and greatly simplifies clock distribution and multi-channel synchronization in complex systems. It is intended to be used by trained professionals in a laboratory environment, and not intended as an end product for commercial use. It can be taken as a complete reference design and customised as required for any end customer applications. Full design details are made available free of charge.

The AD-SYNCHRONA14-EBZ comes in a 1U mechanical form factor. Using popular industry connector SMA and TwinAX interfaces most labs will already have the needed cables.

With its internal OCXO it can operate in standalone mode or be fed from a choice of external sources, such as 3 separate high speed differential clock inputs, a 10MHz reference and 1PPS. This flexibility combined with the capability to select either of the internal VCXO options of 100MHz or 122.88MHz, gives almost unlimited choice for the frequency of interest and accuracy needed for a wide variety of application areas.
