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.
