PRODUCT DESCRIPTION
S3 Package
Modified 16 Pin SOIC
The ACU50752 is a Monolithic GaAs IC designed to
perform the upconverter functions in a double
conversion tuner: gain block, local oscillator and
balanced mixer. The specifications meet the
requirements of CATV, TV and Cable Modem
applications. Offered in a modified 16-lead SOIC
package and requiring only a single polarity 5 V supply
(or 3.5 V, with slightly reduced performance), the IC
is well suited for applications where small size, low
cost, low auxiliary parts count and a no-compromise
performance is important. It provides tuner
manufacturers the opportunity to reduce cost by
lowering the component count and decreasing the
amount of labor-intensive production alignment
steps, while significantly improving performance and
reliability.

ELECTRICAL CHARACTERISTICS
T able 2: Absolute Minimum and Maximum Ratings
T able 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric
performance is guaranteed only over the conditions defined in the electrical
specifications.
Stresses in excess of the absolute ratings may cause permanent damage.
Functional operation is not implied under these conditions. Exposure to absolute
ratings for extended periods of time may adversely affect reliability.
