11-Bit, 200 MSPS, 1.8 V Analog-to-Digital Converter

The AD9230-11 is an 11-bit monolithic sampling analog-to-digital converter (ADC) optimized for high performance, low power, and ease of use. The product operates at up to a 200 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. All necessary functions, including a track-and-hold (T/H) amplifier and voltage reference, are included on the chip to provide a complete signal conversion solution.

The ADC requires a 1.8 V analog voltage supply and a differential clock for full performance operation. The digital outputs are LVDS (ANSI-644) compatible and support twos complement, offset binary format, or Gray code. A data clock output is available for proper output data timing.

Fabricated on an advanced CMOS process, the AD9230-11 is available in a 56-lead lead frame chip scale package, specified over the industrial temperature range (−40°C to +85°C).

Product Highlights

* High Performance. Maintains 62.5 dBFS SNR @ 200 MSPS with a 70 MHz input.

* Low Power. Consumes only 373 mW @ 200 MSPS.

* Ease of Use. LVDS output data and output clock signal allow interface to current FPGA technology. The on-chip reference and sample-and-hold provide flexibility in system design. Use of a single 1.8 V supply simplifies system power supply design.

* Serial Port Control. Standard serial port interface (SPI) supports various product functions, such as data formatting, disabling the clock duty cycle stabilizer, power-down, gain adjust, and output test pattern generation.

* Pin-Compatible Family. 10-bit and 12-bit pin-compatible family offered as AD9211 and AD9230.
