GENERAL DESCRIPTION
The AD9430 is a 12-bit, monolithic, sampling analog-to-digital
converter (ADC) optimized for high performance, low power,
and ease of use. The product operates up to a 210 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
reference, are included on the chip to provide a complete
conversion solution.
The ADC requires a 3.3 V power supply and a differential
ENCODE clock for full performance operation. The digital
outputs are TTL/CMOS or LVDS compatible and support either
twos complement or offset binary format. Separate output
power supply pins support interfacing with 3.3 V CMOS logic.
Two output buses support demultiplexed data up to 105 MSPS
rates in CMOS mode. A data sync input is supported for proper
output data port alignment in CMOS mode, and a data clock
output is available for proper output data timing. In LVDS
mode, the chip provides data at the ENCODE clock rate.
Fabricated on an advanced BiCMOS process, the AD9430 is
available in a 100-lead, surface-mount plastic package
(100 e-PAD TQFP) specified over the industrial temperature
range (–40°C to +85°C).
