PRODUCT DESCRIPTION

The ACD2203 uses both GaAs and Si technology

to provide the downconverter and dual synthesizer

functions in a double conversion tuner gain block,

local oscillator, balanced mixer and dual synthesizer.

The specifications meet the requirements of

CATV/TV/Video and Cable Modem Data applications.

The ACD2203 is supplied in a 28 lead SSOP

package and requires a single +5 V supply voltage.

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

for cost reduction by lowering the component and

packaged IC count and decreasing the amount of

labor-intensive production alignment steps, while

significantly improving performance and reliability.
