The AD9265 is designed to support communications applications where high performance combined with low cost, small size, and versatility is desired.The ADC core features a multistage, differential pipelined architecture with integrated output error correction logic to provide 16-bit accuracy at 125 MSPS data rates and guarantees no missing codes over the full operating temperature range.The ADC features a wide bandwidth differential sample-and-hold analog input amplifier supporting a variety of user-selectable input ranges. It is suitable for multiplexed systems that switch full-scale voltage levels in successive channels and for sampling single-channel inputs at frequencies well beyond the Nyquist rate.Combined with power and cost savings over previously available ADCs, the AD9265 is suitable for applications in communications, instrumentation and medical imaging. A differential clock input controls all internal conversion cycles. A duty cycle stabilizer provides the means to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance over a wide range of input clock duty cycles.

The AD9278 is designed for low cost, low power, small size,and ease of use. It contains eight channels of a variable gain amplifier (VGA) with a low noise preamplifier (LNA); an anti-aliasing filter (AAF); a 12-bit, 10 MSPS to 65 MSPS analog-to-digital converter (ADC); and an I/Q demodulator with programmable phase rotation.Each channel features a variable gain range of 45 dB, a fully differential signal path, an active input preamplifier termination, a maximum gain of up to 51 dB, and an ADC with a conversion rate of up to 65 MSPS. The channel is optimized for dynamic performance and low power in applications where a small package size is critical.The LNA has a single-ended-to-differential gain that is selectable through the SPI. The LNA input noise is typically 1.3 nV/?Hz at a gain of 21.3 dB, and the combined input-referred noise of the entire channel is 1.3 nV/?Hz at maximum gain. Assuming a 15 MHz noise bandwidth (NBW) and a 21.3 dB LNA gain, the input SNR is roughly 88 dB. In CW Doppler mode, each LNA output drives an I/Q demodulator. Each demodulator has independently programmable phase rotation through the SPI with 16 phase settings.The AD9278 requires a LVPECL-/CMOS-/LVDS-compatible sample rate clock for full performance operation. No external reference or driver components are required for many applications.The ADC automatically multiplies the sample rate clock forthe appropriate LVDS serial data rate. A data clock (DCO?) for capturing data on the output and a frame clock (FCO?) trigger for signaling a new output byte are provided.Powering down individual channels is supported to increase battery life for portable applications. A standby mode option allows quick power-up for power cycling. In CW Doppler operation, the VGA, AAF, and ADC are powered down. The power of the TGC path scales with selectable ADC speed power modes.The ADC contains several features designed to maximize flexibility and minimize system cost, such as a programmable clock, data alignment, and programmable digital test pattern generation. The digital test patterns include built-in fixed patterns, built-in pseudo-random patterns, and custom user-defined test patterns entered via the serial port interface.Fabricated in an advanced BiCMOS process, the AD9278 is available in a 10 mm ? 10 mm, RoHS compliant, 144-lead BGA.

Each output has a programmable divider, which can be set to divide by a selected set of integers ranging from 1 to 32. The phase of one clock output relative to another clock output can be set by means of a divider phase select function that serves as a coarse timing adjustment.

The AD9514 does not require an external controller for operation or setup. The device is programmed by means of 11 pins (S0 to S10) using 4-level logic. The programming pins are internally biased to ? VS. The VREF pin provides a level of ? VS. VS (3.3 V) and GND (0 V) provide the other two logic levels.
