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.
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.

Optional features allow users to implement various selectable
operating conditions, including data format select and output
data mode.
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).
PRODUCT HIGHLIGHTS
1.
High performance: Outstanding SFDR performance for mul-
ticarrier, multimode 3G and 4G cellular base station
receivers.
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.
5.
OR (out-of-range) outputs indicate when the signal is beyond
the selected input range.
