PRODUCT DESCRIPTION

The AD9430 is a 12-bit monolithic sampling analog–to–

digital converter with an on–chip track–and–hold circuit and

is optimized for low cost, low power, small size and ease of

use. The product operates up to 170 Msps conversion rate

and is optimized for outstanding dynamic performance in

wideband carrier systems.

The ADC requires a +3.3V power supply and a differential

encode clock for full performance operation. No external

reference or driver components are required for many

applications. The digital outputs are TTL/CMOS or LVDS

compatible. Separate output power supply pins support

interfacing with 3.3V CMOS logic.

An output data format select option of two’s complement or

offset binary is supported. In CMOS mode two output buses

support demultiplexed data up to 85 Msps rates. A data sync

input is supported for proper output data port alignment and

a data clock output is available for proper output data timing.

Fabricated on an advanced BiCMOS process, the AD9430 is

available in a 100 pin surface mount plastic package (100

TQFP ePAD) specified over the industrial temperature range

(–40°C to +85°C).
