GENERAL DESCRIPTION
The AD9230 is a 12-bit monolithic sampling analog-to-digital
converter optimized for high performance, low power, and ease
of use. The product operates at up to a 250 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.
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 AD9230 is
available in a 56-lead LFCSP, specified over the industrial
temperature range (−40°C to +85°C).

PRODUCT HIGHLIGHTS
1. High Performance—Maintains 64.9 dBFS SNR @ 250 MSPS
with a 70 MHz input.
2. Low Power—Consumes only 434 mW @ 250 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—10-bit pin-compatible family
offered as AD9211.
