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
APPLICATIONS
CATV/TV Tuners Cable Modem Tuners 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. Figure 1: Functional Block Diagram

ELECTRICAL CHARACTERISTICS
Table 2: Absolute Minimum and Maximum Ratings Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. Table 3: Operating Ranges The device may be operated safely over these conditions; however, parametric performance is guaranteed only over the conditions defined in the electrical specifications.
