The Most Integrated and Best Sensitivity DVB-S Tuner

The AV2000 is a single chip wide band direct conversion tuner with integrated loop-through optimized for DVB-S (Digital Video Broadcast - Satellite) receiver. It provides excellent performance in applications where maximum sensitivity, higher linearity and large dynamic range are required.

Based on Airoha’s innovative technique, the AV2000 implements direct conversion architecture with embedded LNA (Low Noise Amplifier), Mixer, VCO (Voltage Control Oscillator), Crystal oscillator and LDO (Low Drop-out) regulators. As a result of integrating all these blocks, the AV2000 has the least number of pins compared with other conventional solutions, and requires the least external components.

Not only cost and space, the AV2000 saves time. No calibration procedures are required inside AV2000 during power-on, so the production in customer site could be dramatically speeded up. The AV2000 also features with an integrated loop-through which offers BOM reduction and simplifies the application for dual channel demodulation like watch-and-record.

This cost/performance optimized tuner ICs provided by Airoha makes customers able to come out affordable DVB-S solutions to sell into the market with high competitive advantages.
