ANADIGICS' New Fully Integrated 1GHz Digital Tuner Delivers Exceptional Performance For Space Sensitive Video Applications

WARREN, NJ — ANADIGICS, Inc. (Nasdaq: ANAD) today launched the AIT1042, a fully integrated 1GHz tuner that provides exceptionally high linearity and low noise to deliver crystal clear digital video in today’s densely loaded CATV systems. The device’s high levels of performance and functional integration, combined with its small package size and ease of use, make the AIT1042 an ideal choice for use in the new generation of digital video receivers.

Developed for use in CATV and HDTV tuners, set-top boxes and PC TV tuner cards, the highly integrated AIT1042 minimizes board layout sensitivities, reduces the amount of external circuitry required for a complete receiver solution, and minimizes board layout space. This new RF tuner includes an upconverter with RF gain control, a downconverter, an IF amplifier with gain control, two VCOs and a dual synthesizer, all integrated into a single 7mm x 7mm x 1mm surface mount package.

Operational from a single +5V supply, ANADIGICS’ AIT1042 generates 78 dB of gain while converting a 50 to 1000 MHz RF input signal to a 35 to 50 MHz IF output. The device maintains exceptionally high linearity and low noise over a wide gain control range, which is adjustable up to 40 dB at the RF input and up to 45 dB in the IF amplifier. On-chip oscillator tank circuits reduce component count and eliminate the need for any post assembly manual adjustments.

Ron Michels, Senior Vice President and General Manager of ANADIGICS’ Broadband Business, states, “As the industry migrates toward 1GHz infrastructure and all-digital content, this new tuner delivers the exceptional levels of performance needed to support the high quality video that consumers demand today. In addition, the extremely high level of integration that we have achieved in the AIT1042 makes it ideal for use in space-sensitive applications such as PC TV tuner cards and multiple-tuner set-top boxes.”

The AIT1042 is available now at a price of $3.88 ea. in quantities of 5,000 units. A device evaluation board as well as a complete tuner-demodulator reference design are also available.
