摘要
Provided is an analog front end of a digital TV, a digital TV system having the same, and a method of operating the same. The analog front end includes: a first selection circuit which selectively outputs differential sound intermediate frequency signals or differential TV broadcast signals in response to a first selection signal; a second selection circuit which outputs a clock signal among a plurality of clock signals having a different sampling frequencies, in response to a second selection signal; and an analog-to-digital converter which converts output signals output from the first selection circuit to a digital code, according to a sampling frequency of a clock signal output from the second selection circuit.
