PRODUCT DESCRIPTION
TheACD2203 uses both GaAs and Si technology
to provide the downconverter and dual synthesizer
functions of a double conversion tuner. The
performanceoftheincludedlocaloscillator,balanced
mixer and synthesizers meet the requirements for
CATV/TV/VideoandCableModemapplications.The
ACD2203issuppliedinaRoHScompliant28lead
SSOP package and requires a single +5 V supply
voltage.TheICiswellsuitedforapplicationswhere
smallsize,lowcost,lowauxiliarypartscountanda
no-compromiseperformanceisimportant.Itprovides
for cost reduction by lowering the component and
packaged IC count and decreasing the amount of
labor-intensive production alignment steps, while
significantlyimprovingperformanceandreliability.
