Zero-IF architecture
Low noise figure 3 dB
Typical AGC dynamic range: -102 dBm to +10 dBm
Low current consumption in continuous mode
VHF: 54 mA, UHF: 57 mA
Dynamic power control embedded
Includes on-chip features
Fast switching fractional-N PLL
Low phase noise and wide frequency range VCO
Integrated PLL loop filter
Bandwidth-adjustable low-pass filter
Reference clock output for demodulators

The ADMTV804 has an additional feature of an on-chip LDO enables 3 V single power supply

"Analog Devices has shipped approximately 20 million RF tuners worldwide and has had market share leadership in China since 2007, when ADI sold the world's first CMMB tuner into the Chinese mobile TV market; today, most CMMB terminals have ADI RF tuners inside," said Brian Kim, general manager, Integrant Technologies Division, Analog Devices. "The success ADI has experienced, not only in China but in Korea and Japan as well, has served as the springboard for an expanded class of RF tuners to satisfy emerging U.S. and European mobile TV standards. ADI has developed chips that allow consumers in any part of the world - using any mobile TV broadcasting standard -- to enjoy the highest quality reception while on the move."
