The TV Tuner is a highly integrated CMOS single-chip, direct down-conversion tuner IC for digital TV standards such as DTMB,CMMB. The tuner IC covers UHF IV,V bands(470-862MHz), it features low power consumption and low number of external components. It includes LNA, RF PGAs, down-conversion mixer, RF/BB RSSI and digitally adjustable automatic gain control circuitries, an adjustable channel select filter with onchip bandwidth calibration, BB programmable gain amplifiers, VCOs with a high resolution fractional-N PLL, digital controlled crystal oscillator (DCXO), and digital interface/control circuits. The tuner IC supports 3-wire
Serial Interface and I2C compatible serial interface. The internal DCXO makes it cost competitive.
The tuner is manufactured in CMOS technology and hosted in QFN32 package.
