Low-jitter 1.25-GSPS clock optimizes JESD204B serial interface functionality in GSPS data converter applications
New clock IC enables the unique functionality of the JESD204B SERDES high-speed interface Norwood, MA (12/02/2014) – AD9528 provides a low-power, multi-output, clock distribution function with low-jitter performance, along with an on-chip, two-stage PLL and VCO. The on-chip VCO tunes from 3.6 GHz to 4.0 GHz, with the input receivers and oscillator providing both single-ended […]
One chip, any temperature sensor — IC digitizes all temp. sensors
A chip called the LTC2983 directly digitizes RTDs, thermocouples, thermistors and external diodes with 0.1°C accuracy and 0.001°C resolution. The device combines low-noise and low-offset-buffered ADCs with excitation and control circuits for each type of sensor. The chip precisely measures absolute microvolt-level signals from thermocouples and ratiometric resistance measurements from RTDs and thermistors, linearizes the results […]
FDAs handle 7 GHz signals
Texas Instruments announced two new fully differential amplifiers (FDAs) that provide DC-coupled applications with best-in-class AC performance to improve system capabilities and performance. The LMH3401 and LMH5401 FDAs provide higher bandwidth and slew rate, and lower distortion than existing ADC drivers. The performance of the LMH3401 and LMH5401 can enable radar systems that help keep […]

Smart meter transceiver works on dual bands
Atmel Corporation, a global leader in microcontroller (MCU) and touch solutions, announced a new family of wireless transceivers. Atmel’s AT86RF215, the first sampling device, is the industry’s first dual-band sub-1GHz / 2.4GHz transceiver compliant to IEEE 802.15.4g-2012 and ETSI TS 102 887-1. Expanding the Atmel SMART metering portfolio, the new devices include the AT86RF215M, a […]
Choosing, using and designing oscillators
Most electronics today have oscillators in them. Digital circuitry needs a clock. Radio frequency signals require an oscillator or clock. Some analog circuitry also needs a clock or oscillating signal source. If you are using a microcontroller then it might have a built-in clock, although it may not be accurate enough, depending on your application, […]
Low Power Conversion for Energy Harvesting
by Tony Armstrong, Director of Product Marketing, Linear Technology Corporation There is plenty of ambient energy in the world around us and the conventional approach for energy harvesting has been through solar panels and wind generators. However, new harvesting tools allow us to produce electrical energy from a wide variety of ambient sources. Furthermore, it is not the […]
