Single Chip Tuner for DVB-S/ABS-S Receiver
AV2026 is a highly integrated single chip for DVB-S/ABS-S Tuner receiver application. The input RF signal frequency ranges from 850MHz to 2300MHz. AV2026 implements zero-IF direct conversion architecture with embedded LNA, Mixer, VCO, crystal oscillator and LDO regulators to minimize the external BOM cost. There is no additional calibration procedure required in AV2026 during power-on procedures. A programmable baseband channel filter is also implemented to provide different channel bandwidths from 4MHz to 40MHz. A 27MHz reference clock with on-chip buffer is also provided for the baseband section clock source. A simple 2-wire interface allows easy control from the baseband controller.
