ACU50752 CATV/TV/Cable Modem Upconverter MMIC Data Sheet - Rev 0.0 FEATURES · · · · · · · · · · · · Integrated Monolithic Upconverter Compatible with all digital and analog modulation types 5 Volt Operation Low Power Consumption Low Noise Figure High Conversion Gain Low Distortion Excellent Oscillator Purity and Phase Noise Remote Shutdown Feature Small Size Low Cost High Reliability S3 Package Modified 16 Pin SOIC PRODUCT DESCRIPTION The ACU50752 is a Monolithic GaAs IC designed to perform the upconverter functions in a double conversion tuner: gain block, local oscillator and balanced mixer. The specifications meet the requirements of CATV, TV and Cable Modem applications. Offered in a modified 16-lead SOIC package and requiring only a single polarity 5 V supply (or 3.5 V, with slightly reduced performance), 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 tuner manufacturers the opportunity to reduce cost by lowering the component count and decreasing the amount of labor-intensive production alignment steps, while significantly improving performance and reliability.
