GENERAL DESCRIPTION
The AD9446 is a 16-bit monolithic, sampling analog-to-digital
converter (ADC) with an on-chip track-and-hold circuit. It is
optimized for power, small size, and ease of use. The product
w operates at up to a 100 MSPS conversion rate and is optimized
for multicarrier, multimode receivers, such as those found in
w cellular infrastructure equipment.
wThe ADC requires 3.3 V and 5.0 V power supplies and a low
.Dvoltage differential input clock for full performance operation.
No external reference or driver components are required for
amany applications. Data outputs are LVDS-compatible (ANSI-
t644) or CMOS-compatible and include the means to reduce
athe 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 AD9446 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. True 16 bit linearity.
2. High performance: outstanding SFDR performance for multi-
carrier, multimode 3G and 4G cellular base station receivers.
3. Ease of use: on-chip reference and track-and-hold. An
output clock simplifies data capture.
4. Packaged in a Pb-free, 100-lead TQFP/EP.
5. Clock duty cycle stabilizer (DCS) maintains overall ADC
performance over a wide range of clock pulse widths.
6. OR (out-of-range) outputs indicate when the signal is beyond
the selected input range.
