THÔNG SỐ KỸ THUẬT CỦA CHÍNH TEA5767

■ High sensitivity due to integrated low-noise RF input amplifier

■ FM mixer for conversion to IF of the US/Europe (87.5 MHz to 108 MHz) and Japanese (76 MHz to 91 MHz) FM band

■ Preset tuning to receive Japanese TV audio up to 108 MHz

■ RF Automatic Gain Control (AGC) circuit

■ LC tuner oscillator operating with low cost fixed chip inductors

■ FM IF selectivity performed internally

■ No external discriminator needed due to fully integrated FM demodulator

■ Crystal reference frequency oscillator; the oscillator operates with a 32.768 kHz clock crystal or with a 13 MHz crystal and with an externally applied 6.5 MHz reference frequency

■ Phase-locked loop (PLL) synthesizer tuning system

■ I 2C-bus and 3-wire bus, selectable via pin BUSMODE

■ 7-bit IF counter output via the bus

■ 4-bit level information output via the bus

■ Soft mute

■ Signal dependent mono to stereo blend [Stereo Noise Cancelling (SNC)]

■ Signal dependent High Cut Control (HCC)

■ Soft mute, SNC and HCC can be switched off via the bus

■ Adjustment-free stereo decoder

■ Autonomous search tuning function

■ Standby mode

■ Two software programmable ports

■ Bus enable line to switch the bus input and output lines into 3-state mode
