AIT1042

The AIT1042 Integrated Digital Tuner with RF and IF Gain Control is a complete 1 GHz bandwidth tuner IC specifically designed to support digital video and data applications. It combines GaAs and Silicon technology to integrate the upconverter, downconverter, VCO, synthesizer, IF amplifier, RF gain control and IF gain control functions of a double-conversion tuner into one small package.

The exceptional linearity and low noise figure of the AIT1042 are ideal for use with today's CATV systems with densely loaded spectrum. With integrated oscillator tank circuits, the AIT1042's high level of integration minimizes board layout sensitivities and the amount of external circuitry required for a complete receiver solution. The integrated IF output further enables system solutions that minimize board layout space.The device operates from a single +5 V supply, and incorporates a programmable power-down mode.

The AIT1042 is offered in a small 7 mm x 7 mm x1 mm, 48 pin, RoHS compliant, surface mount package ideal for space-sensitive applications such as PC cards and multiple-tuner set-top boxes.
