ACU2109 Wideband Tuner Upconverter Data Sheet - Rev 2.5 FEATURES • Integrated Monolithic GaAs Upconverter • Designed for Digital and Analog TV Tuners • Very Low Oscillator Phase Noise • Low Noise Figure and Low Distortion • Low Power Consumption • Small Size • Can be Shut Down Remotely • Operates from 5 Volt Power Supply • High Reliability • RoHS-Compliant Package APPLICATIONS • CATV/TV Tuners • Cable Modem Tuners S3 Package Modified 16 Pin SOIC PRODUCT 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. This upconverter IC is well suited for double conversion tuner designs in which small size and high performance for both Digital and Analog TV signals is important. It allows tuner manufacturers to reduce costs by lowering component count and dispensing with labor intensive production alignment steps, while improving performance and reliability. The part is offered in a low profile 16-lead modified SOIC package, and it requires only a single +5 Volt power supply.
