Analog Devices Inc. AD9626BCPZ-250

Description
The AD9626 is a 12-bit, high-performance analog-to-digital converter (ADC) designed for wideband carrier and broadband systems. It operates at conversion rates up to 250 MSPS and features excellent dynamic performance, including a signal-to-noise ratio (SNR) of 64.8 dBFS at 70 MHz input frequency and an effective number of bits (ENOB) of 10.5 at 70 MHz input frequency (-1.0 dBFS).
The AD9626 incorporates a track-and-hold (T/H) and voltage reference on-chip, providing a complete signal conversion solution. It requires a 1.8 V analog voltage supply and a differential clock for full performance operation. The digital outputs are CMOS compatible and support various data formats, including offset binary, twos complement, and Gray code. A data clock output is also available for proper output data timing.

Features
High performance: SNR of 64.8 dBFS at 70 MHz input frequency at 250 MSPS, ENOB of 10.5 at 70 MHz input frequency (-1.0 dBFS)
Low power: Consumes only 364 mW at 250 MSPS
Ease of use: CMOS output data and output clock signal allow interface to current FPGA technology. On-chip reference and sample-and-hold provide flexibility in system design. Single 1.8 V supply simplifies system power supply design.
Serial port control: Standard serial port interface supports various product functions, such as data formatting, clock duty cycle stabilizer, power-down, gain adjust, and output test pattern generation.
Pin-compatible family: 10-bit pin-compatible family offered as the AD9601.

Applications
Wireless and wired broadband communications
Cable reverse path
Communications test equipment
Radar and satellite subsystems
Power amplifier linearization
