Warren, N.J. ANADIGICS, Inc. reports that it has introduced new digital and analog tuners that provide RF front-end functionality in the industry's smallest package size. The AIT1010 and AIT1021 devices are optimized for performance and space savings in cable and terrestrial broadband tuning applications, including digital television (DTV) and high definition television (HDTV).
The AIT1010 digital and analog video tuner is suited for digital and analog television applications, including multi-tuner DVRs/PVRs operating in mixed signal environments. The AIT1021 digital video and data tuner provides exceptional performance for digital television applications, including off-air digital receivers.
These tuners feature a conversion gain of 36 dB, which minimizes the need for external amplifiers. The AIT1021 also offers integrated RF gain control over a 25 dB range, which eliminates the need for external PIN-diode gain control circuitry. The tuners operate from a single +5 VDC supply, offer two-wire serial programming for compatibility with fast I2C buses, and provide four selectable device addresses for use in multi-tuner applications. They use a double-conversion architecture and support a range of first IF frequencies, which reduces interference for multi-tuner applications.
The devices are housed in 40 pin 6 mm by 6 mm by 1 mm surface-mount packages
The AIT1010 is priced at $2.50 and the AIT1021 is priced at $2.00 each in 10,000-piece quantities. Samples are available now. Anadigics,
