GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The AD9211 is a 10-bit monolithic sampling analog-to-digital
converter optimized for high performance, low power, and ease
of use. The product operates at up to a 300 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) and voltage
reference, are included on the chip to provide a complete
signal conversion solution.
1. High Performance—Maintains 60.1 dBFS SNR @
300 MSPS with a 70 MHz input.
2. Low Power—Consumes only 410 mW @ 300 MSPS.
3. 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.
4. Serial Port Control—Standard serial port interface
supports various product functions, such as data
formatting, disabling the clock duty cycle stabilizer, power-
down, gain adjust, and output test pattern generation.
5. Pin-Compatible Family—12-bit pin-compatible family
offered as AD9230.
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 either
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 AD9211 is
available in a 56-lead LFCSP, specified over the industrial
temperature range (−40°C to +85°C).
