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
