Broadband wireless

The AD9444 is available in a 100-lead surface-mount plastic

package (100-lead TQFP/EP) specified over the industrial

temperature range (−40°C to +85°C).

Radar, infared imaging

Communications instrumentation

PRODUCT HIGHLIGHTS

1. High performance: Outstanding SFDR performance for mul-

ticarrier, multimode 3G and 4G cellular base station

receivers.

GENERAL DESCRIPTION

The AD9444 is a 14-bit monolithic, sampling analog-to-digital

converter (ADC) with an on-chip, track-and-hold circuit and is

optimized for power, small size, and ease of use. The product

operates at up to an 80 MSPS conversion rate and is optimized

for multicarrier, multimode receivers, such as those found in

cellular infrastructure equipment.

2. Ease of use: On-chip reference and track-and-hold. An

output clock simplifies data capture.

3. Packaged in a Pb-free, 100-lead TQFP/EP.

4. Clock DCS maintains overall ADC performance over a wide

range of clock pulse widths.

The ADC requires 3.3 V and 5.0 V power supplies and a low

voltage differential input clock for full performance operation.

No external reference or driver components are required for

many applications. Data outputs are LVDS-compatible (ANSI-

644) or CMOS-compatible and include the means to reduce

the overall current needed for short trace distances.

5. OR (out-of-range) outputs indicate when the signal is beyond

the selected input range.
