| A FEATURES * * * * * * * * * Integrated Monolithic GaAs Upconverter Designed for Digital and Analog TV Very Low Oscillator Phase Noise Low Noise Figure & Low Distortion Low Power Consumption Small size Can be Shut Down Remotely Operates from 5 Volt Power Supply High Reliability ACU2109S3 CATV/TV/Cable Modem Upconverter MMIC Advanced Product Information - Rev 1 APPLICATIONS * * CATV/TV Tuners Cable Modem Tuners S3 16 Pin SOIC Package Description: The ACU2109 is a Monolithic GaAs IC incorporating all upconverter functions of a double conversion CATV, Cable Modem and TV tuner: gain block, oscillator and a double balanced mixer. The oscillator is optimized to meet the stability and phase noise requirements of 256QAM Digital TV, while the amplifier and mixer retain the low distortion necessary for Analog signals. The part is supplied in a low profile 16-lead modified SOIC package and it requires only a single polarity 5 Volt power supply. This upconverter IC is well suited for double conversion tuner designs ABSOLUTE MAXIMUM RATINGS where small size, low cost, low auxiliary parts count and a no-compromise performance when PARAMETER ABSOLUTE MAXIMUM handling both Digital and Analog TV VDD/VI F /VOSC (Pi ns 1,10,14,& 16) 9 V DC signals is important.
