The LTC2000 is a family of 16-/14-/11-bit 2.5Gsps current steering DACs with exceptional spectral purity.The single (1.25Gsps mode) or dual (2.5Gsps mode) port source synchronous LVDS interface supports data rates of up to 1.25Gbps using a 625MHz DDR data clock, which can be either in quadrature or in phase with the data. An internal synchronizer automatically aligns the data with the DAC sample clock.Additional features such as pattern generation, LVDS loopout and junction temperature sensing simplify system development and testing.A serial peripheral interface (SPI) port allows configuration and read back of internal registers. Operating from 1.8V and 3.3V supplies, the LTC2000 consumes 2.2W at 2.5Gsps and 1.3W at 1.25Gsps.Applications Broadband Communication Systems DOCSIS CMTS Direct RF Synthesis Radar Instrumentation Automatic Test Equipment

Demonstration circuit 2307A is a high input voltage protected high side MOSFET driver featuring the LT1910ES8. This demo board has a wide input voltage range from 8V to 48V and is capable of protecting a voltage source against a short circuit. The LT1910 has a 50mV trip point for the selection of the current sense resistor RS1. The value of RS1 is 0.01Ω in this demo board which allows the output to deliver up to 5A. However, the RS1 footprint supports multiple sizes and can be replaced with up to a 2W device.

The LTC3370 is a highly flexible multioutput power supply IC. The device includes four synchronous buck converters, configured to share eight 1A power stages, each of which is powered from independent 2.25V to 5.5V inputs.The DC/DCs are assigned to one of eight power configurations via pin programmable C1-C3 pins. The common buck switching frequency may be programmed with an external resistor, synchronized to an external oscillator, or set to a default internal 2MHz clock.The operating mode for all DC/DCs may be programmed via the PLL/MODE pin for Burst Mode or forced continuous mode operation. A PGOODALL output indicates when all enabled DC/DCs are within a specified percentage of their final output value.To reduce input noise, the buck converters are phased in 90? steps. Precision enable pin thresholds facilitate reliable power-up sequencing. The LTC3370 is available in a 32-lead 5mm ? 5mm QFN package.Applications General Purpose Multichannel Power Supplies:?Automotive, Industrial, Distributed Power Systems

The ADF4355 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 frequency. A series of frequency dividers permits operation from 54 MHz to 6800 MHz.The ADF4355 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allow the user to generate radio frequency (RF) output frequencies as low as 54 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin and software controllable.Control of all on-chip registers is through a simple 3-wire interface. The ADF4355 operates with analog and digital power supplies ranging from 3.15 V to 3.45 V, with charge pump and VCO supplies from 4.75 V to 5.25 V. The ADF4355 also contains hardware and software power-down modes.Applications Wireless infrastructure (W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, DECT) Point to point/point to multipoint microwave links Satellites/VSATs Test equipment/instrumentation Clock generation
