The AD91661 is a high performance, wideband, on-chip vector signal generator composed of a high speed JESD204B serializer/deserializer (SERDES) interface, a flexible 16-bit digital datapath, a inphase/quadrature (I/Q) digital-to-analog converter (DAC) core, and an integrated differential to single-ended outputbuffer amplifier, matched to a 50 ? load up to 10 GHz.The DAC core is based on a quad-switch architecture, which is configurable to increase the effective DAC core update rate of up to 12.8 GSPS from a 6.4 GHz DAC sampling clock, with an analog output bandwidth of true dc to 9.0 GHz, typically. The digital datapath includes multiple interpolation filter stages, a direct digital synthesizer (DDS) block with multiple numerically controlled oscillators (NCOs) supporting fast frequency hopping (FFH), and additional FIR85 and inverse sinc filter stages to allow flexible spectrum planning.The differential to single-ended buffer eliminates the need for a wideband balun, and supports the full analog output bandwidth of the DAC core. DC coupling the output allows baseband waveform generation without the need for external bias tees or similar circuitry, which makes the AD9166 uniquely suited for the mostdemanding high speed ultrawideband RF transmit applications. The various filter stages enable the AD9166 to be configured for lower data rates, while maintaining higher DAC clock rates to ease the filtering requirements and reduce the overall system size, weight, and power.The data interface receiver consists of up to eight JESD204B SERDES lanes, each capable of carrying up to 12.5 Gbps. To enable maximum flexibility, the receiver is fully configurable according to the data rate, number of SERDES lanes, and lane mapping required by the JESD204B transmitter.In 2? nonreturn-to-zero (NRZ) mode of operation (with FIR85 enabled), the AD9166 can reconstruct RF carriers from true dc to the edge of the third Nyquist zone, or an analog bandwidth of true dc up to 9 GHz.In mix mode, the AD9166 can reconstruct RF carriers in the second and third Nyquist zones while consuming lower power and maintaining a performance comparable to 2? NRZ mode.In baseband modes, such as return-to-zero (RZ) and 1? NRZ, the AD9166 is ideal to reconstruct RF carriers from true dc to the edge of the first Nyquist zone while consuming lower power compared to 2? NRZ mode.The quadrature DDS block can be configured as a digital upconverter to upconvert I/Q data samples to the desired location across the spectrum, in all three Nyquist zones.The DDS also consists of a bank of 32 numerically controlled oscillators (NCOs), each with its own 32-bit phase accumulator. When combined with a 100 MHz serial peripheral interface (SPI), the DDS allows a phase coherent FFH, with a phase settling time as low as 300 ns.The AD9166 is configured using a common SPI interface that monitors the status of all registers. The AD9166 is offered in a 324-ball, 15 mm ? 15 mm, 0.8 mm pitch BGA_ED package.Product Highlights High dynamic range and signal reconstruction bandwidth supports RF signal synthesis of up to 9 GHz. Fully supports zero IF and other dc-coupled applications.

Demonstration circuit 2365A highlights the LTC2358 family of buffered input ADCs. The LTC2358/LTC2357/LTC2353/LTC2333 are low noise, high speed, 16-/18-bit successive approximation register (SAR) ADCs with integrated front end buffers. These ADCs accept a wide common mode range. Pico-amp inputs and high CMRR enable these ADCs to connect directly to a wide range of sensors without compromising measurement accuracy. The demo manual refers to the LTC2358-18 but applies to all parts in the family, the only differences being the number of bits, number of channels and the maximum sample rate. The LTC2358-18 has a flexible SoftSpan™ interface that allows conversion-by-conversion control of the input voltage span on a per-channel basis. An internal 2.048V reference and 2X buffer simplify basic operation while an external reference can be used to increase the input range and the SNR of the ADC.

The AD9234 is a dual, 12-bit, 1 GSPS/500 MSPS ADC. The device has an on-chip buffer and sample-and-hold circuit designed for low power, small size, and ease of use. This product is designed for sampling wide bandwidth analog signals. The AD9234 is optimized for wide input bandwidth, high sampling rate, excellent linearity, and low power in a small package.The dual ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth buffered inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. Each ADC data output is internally connected to an optional decimate-by-2 block. The AD9234 has several functions that simplify the automatic gain control (AGC) function in a communications receiver.?The programmable threshold detector allows monitoring of the incoming signal power using the fast detect output bits of the ADC. If the input signal level exceeds the programmable threshold, the fast detect indicator goes high. Because this threshold indicator has low latency, the user can quickly turn down the system gain to avoid an overrange condition at the ADC input. In addition to the fast detect outputs, the AD9234 also offers signal monitoring capability. The signal monitoring block provides additional information about the signal being digitized by the ADC.Users can configure the Subclass 1 JESD204B-based high speed serialized output in a variety of one-, two-, or four-lane configurations, depending on the acceptable lane rate of the receiving logic device and the sampling rate of the ADC. Multiple device synchronization is supported through the SYSREF? and SYNCINB? input pins.The AD9234 has flexible power-down options that allow significant power savings when desired. All of these features can be programmed using a 1.8 V to 3.3 V capable 3-wire SPI.The AD9234 is available in a Pb-free, 64-lead LFCSP and is specified over the ?40?C to +85?C industrial temperature range.
