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.
