“The Final Choice for Mobile TV Front End”
Analog Single IC RF Tuner/Demodulator with Class-leading Performance
The ATV168 is a System-on-Chip (SoC) integrated Circuit (IC) that demodulates PAL,NTSC, SECAM and analog TV and FM radio. The NMI601 is a
single-chip solution that implements the RF tuner, demodulator, and peripherals on a single die.
The ATV168 is a PAL/NTSC/SECAM/FM receiver that implements the RF tuner and digital demodulator on the same die. ATV168 receives an input
single-ended RF signal from the antenna through the VHF-I/FM, VHF-III, or UHF-band RF input. The tuner integrates the LNAs, mixers, VCO, PLL/loop
filter, LO generation, crystal oscillator, baseband filters and amplifiers, and analog-digital converters.
The tuner also includes an innovative closed loop RF gain control. The demodulator receives a baseband input from the tuner and provides an Automatic
Gain Control(AGC) signal to control the tuner gain. The demodulator implements the full acquisition, synchronization, and demodulation for PAL, NTSC,
SECAM, and FM transmission. The ATV168 communicates with the host via the I²C interface for control, the BT.601 camera interface for video, and the
I2S interface for audio.
An analog audio output is also provided as an alternative to the I²C audio interface.
