Integrated tuner eases switch to digital
Device provides the low noise and low distortion performance required for CATV systems that combine digital and analogue channels using a densely loaded spectrum.
The Anadigics AIT1032 is a fully integrated 1GHz tuner that enables crystal-clear video in CATV set-top boxes, DVRs, PC TV tuner cards and other tuner-onboard applications Incorporating the upconvertor, downconvertor, VCO, synthesiser, 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 superb video quality in today's CATV systems that combine digital and analogue channel lineups together using a densely loaded spectrum

Active splitter ICs enable multi-output boxes
Active splitters for use in CATV set-top boxes with multiple tuners incorporate highly linear low-noise amplifiers to drive multiple output paths.
Amplifier supports faster Docsis datarates
Device supports high linear power levels, which enable channel bonding and thus higher datarates in the cable system upstream (return) path.
Ron Michels, Senior Vice President and General Manager of Anadigics' Broadband Business, reports: "Anadigics' AIT1032 is a complete RF tuner solution which employs such a high degree of integration that it significantly reduces the amount of external circuitry required, while at the same time providing a robust, high-performance solution that minimises sensitivity to board layout variations".
"As the industry moves toward a fully digital video delivery, the performance of this double conversion tuner will enable set-top box designers to make the transition from analogue to digital architectures without dramatically changing their product designs".
The AIT1032 provides two 45MHz IF outputs, one for analogue signals and one for digital signals.
The digital output offers 78dB (typical) conversion gain, with an adjustable IF amplifier stage having 45dB of gain control range.
The analogue 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 optimised to avoid interference in MoCA-enabled applications The AIT1032 operates from a single +5V supply and is available with a full reference design.
Offered in a 7 x 7 x 1mm 48-pin surface mount package, it is available now at a price of US $4.31 in quantities of 5000 units.
