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 ADT7310 is a high accuracy digital temperature sensor in a narrow SOIC package. It contains a band gap temperature reference and a 13-bit ADC to monitor and digitize the temperature to a 0.0625?C resolution. The ADC resolution, by default, is set to 13 bits (0.0625 ?C). This can be changed to 16 bits (0.0078 ?C) by setting Bit 7 in the configuration register (Register Address 0x01).The ADT7310 is guaranteed to operate over supply voltages from 2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typically 210 ?A. The ADT7310 has a shutdown mode that powers down the device and offers a shutdown current of typically 2 ?A. The ADT7310 is rated for operation over the ?55?C to +150?C temperature range.The CT pin is an open-drain output that becomes active when the temperature exceeds a programmable critical temperature limit. The default critical temperature limit is 147?C. The INT pin is also an open-drain output that becomes active when the temperature exceeds a programmable limit.

DC1383A-A: Demo Board for the LTC2451 Ultra-Tiny, 16-Bit ΔΣ ADC with I2C Interface

Demonstration circuit 1311 is a Telecom isolated DC/DC converter featuring the LTC3805/-5 constant frequency current mode flyback controller. The DC1311 converts 18V to 72V input voltage to an isolated 3A of output current at 3.3V. The 300kHz constant frequency operation is maintained down to very light load to reduce low frequency noise generated over a wide range of load current. The converter provides high output voltage accuracy (typically ±2%) over wide load range with no minimum load requirement. The DC1311 also provides non-isolated design by removing opto coupler and LTC4430 circuit. The demonstration circuit can be easily modified to generate different output voltages up to 15V. As output voltage is increased, the maximum output current must be reduced to limit the output power to no more than 10W.

The ADXL344 Development Board is an easy-to-use tool designed to shorten application development time by providing a ready-to-use platform for data collection and firmware development. The board is pre-configured as a datalogger that can be used to gather data for refining algorithms, tuning thresholds, and generally familiarizing oneself with accelerometer data. Powered by two AAA batteries, the board is completely untethered and integrates seamlessly into portable applications. Logged data is stored on a MicroSD memory card, providing essentially unlimited memory capacity and operating system versatility.

Additionally, the board is fully programmable, providing a hardware platform on which firmware can be tested in parallel with development of application hardware. Communications and processing are performed by an ARM7-based ADuC7024 micro-controller, and firmware is written in C. A programming cable is provided with the board, and a development environment and header files are supplied on this page. Finally, the platform can be duplicated in the final application, having already been tested with the application firmware. Schematics and layout can be found under the Supporting Documentation tab and can be used freely in your application. Note that this board is not configured to display real-time data.
