high IF sampling mode, and output data mode.

3.3 V and 5 V supply operation

The AD9445 is available in a Pb-free, 100-lead, surface-mount,

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

industrial temperature range −40°C to +85°C.

APPLICATIONS

Multicarrier, multimode cellular receivers

Antenna array positioning

Power amplifier linearization

Broadband wireless

PRODUCT HIGHLIGHTS

1. High performance: outstanding SFDR performance for IF

sampling applications such as multicarrier, multimode 3G,

and 4G cellular base station receivers.

Radar

Infrared imaging

Medical imaging

Communications instrumentation

2. Ease of use: on-chip reference and high input impedance

track-and-hold with adjustable analog input range and an

output clock simplifies data capture.

GENERAL DESCRIPTION

The AD9445 is a 14-bit, monolithic, sampling analog-to-digital

converter (ADC) with an on-chip IF sampling track-and-hold

circuit. It is optimized for performance, small size, and ease of

use. The product operates at up to a 125 MSPS conversion rate

and is designed for multicarrier, multimode receivers, such as

those found in cellular infrastructure equipment.

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

4. Clock duty cycle stabilizer (DCS) maintains overall ADC

performance over a wide range of clock pulse widths.

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

beyond the selected input range.

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 CMOS or LVDS

6. RF enable pin allows users to configure the device for

optimum SFDR when sampling frequencies above 210 MHz

(AD9445-125) or 240 MHz (AD9445-105).

compatible (ANSI-644 compatible) and include the means to

reduce the overall current needed for short trace distances.
