AD7606 , AD7607 simultaneous-sampling ADCs

Analog Devices introduced (analog-to-digital converters) that simplify the design of next-generation power-line-monitoring systems. The need for more efficient utility substations and “smart grid” management is growing as worldwide electricity demand increases.
AD7606 , AD7607 simultaneous-sampling ADCs provide the resolution and performance needed for next-generation power-line-monitoring system designs that ensure the reliable delivery of electricity to millions of people in nearly all corners of the world,” said Leo McHugh, product line director, precision signal processing, Analog Devices. “
Available in six- or four-channel options, ADI’s 16-bit, eight-channel AD7606 and 14-bit, eight-channel AD7607 simultaneous-sampling ADCs achieve SNR (signal-to-noise ratio) performance of 90 dB.
The AD7606 and AD7607 simultaneous-sampling ADCs operate on a 5-V analog supply, 1.8-V to 5-V logic supply, and feature a front-end, anti-alias filter with high input impedance and input clamp to ±16.5-V. In addition, an internal reference and a reduced decoupling capacitor requirement provide a higher level of integration compared to alternative solutions. The new devices offer true bipolar analog input ranges of ±5 V and ±10 V that allow for the preservation of phase information while sampling bipolar voltages and currents over a wide dynamic range.
The AD7606 and AD7607 simultaneous-sampling ADCs contain on-chip LDOs (low-drop-out regulators), a reference and reference buffer, track-and-hold circuitry, signal-conditioning circuitry, on-chip conversion clock, and high-speed parallel and serial interfaces. The AD7606 and AD7607 simultaneous-sampling ADCs integrate a front-end, anti-alias filter with attenuation of approximately 40 dB while sampling at a fast throughput rate up to 200 kSPS. The conversion process and data acquisition are controlled using CONVST signals and an internal oscillator. Two CONVST pins allow the simultaneous sampling of all eight analog inputs or two groups of four analog input channels to allow for phase differences

Analog Devices announced of new integrated RF-to-digital baseband transceivers. The AD9356 and AD9357 integrated transceivers advance low-cost base-station designs and deployments for 4G technology, such as WiMAX and LTE (long term evolution).

“Today’s WiMAX and LTE infrastructure equipment generally rely on a multitude of discrete components, often exceeding power budgets while missing time-to-market goals,” said Tom Gratzek, product line director, WiMAX Transceiver Group, Analog Devices. “Typical picocell base-station transceivers comprise six to eight active components, while microcell base stations can easily require double this component count. Designs that exploit ADI’s new AD9356 and AD9357 integrated transceivers can reduce the component count for a 2x2 transceiver to a single device, while cutting power consumption by at least 50 percent.”

The new transceivers’ configurability allows designers to develop and maintain configurable software to support multiple platforms .
The AD9356 and AD9357 transceivers integrate 12-bit ADCs, DACs, complete RF-receive and RF-transmit signal chains, and on-chip frequency synthesizers. Embedded real-time control and calibration loops significantly reduce factory calibration and test times. The transmitter’s signal-to-noise ratio provides support for picocells and microcells from +13 dBm up to +36 dBm output power at the antenna port, while meeting the demanding requirements for 4G base stations. Designers can optimize receiver performance by configuring the transceivers to use a flexible, on-chip AGC (automatic gain control) algorithm.
The AD9356 and AD9357 transceivers support the 2.3-to-2.7-GHz and 3.3-to-3.8-GHz ranges, respectively, covering existing WiMAX bands and channel bandwidths of 3.5, 4.375, 5, 7, 8.75 and 10 MHz.
