Warren, N.J.—ANADIGICS Inc. has launched the AIT1032, a fully integrated, 1-GHz tuner that enables crystal-clear video in CATV set-top boxes, DVRs, PC TV tuner cards, and other tuner-on-board applications.
Incorporating the upconverter, downconverter, VCO, synthesizer, RF and IF amplifier, and RF and IF gain control functions into a single package, the device provides the low noise and low distortion performance required for high video quality in today's CATV systems that combine digital and analog channel lineups together using a densely loaded spectrum.
The AIT1032 provides two 45 MHz IF outputs, one for analog signals and one for digital signals. The digital output offers 78dB (typ) conversion gain, with an adjustable IF amplifier stage having 45dB of gain control range. The analog output provides 65dB conversion gain via a fixed IF output amplifier. The single RF input to the device contains a low noise amplifier with 35dB of gain control range. The device includes on-chip oscillator tank circuits that reduce component count and eliminate the need for any post-assembly manual adjustments. The AIT1032 is optimized to avoid interference in MoCA-enabled applications
The AIT1032 operates from a single +5V supply and is available with a full reference design. It is offered in a 7mm x 7mm x 1 mm 48-pin surface mount package.
