TEA6824中文资料Front-end and PLL synthesizers for car radios数据手册恩XP规格书

描述 Description

GENERAL DESCRIPTION
The TEA6824T together with the TEA6810T forms the receiver part of an AM/FM electronically tuned car radio
providing FM MPX signal and AM AF signal for Car Digital Signal Processor (CDSP) applications.FEATURES
• FM mixer for conversion from FM-IF1 = 72.2 MHz to FM-IF2 = 10.7 MHz
• AM mixer for conversion from AM-IF1 = 10.7 MHz to AM-IF2 = 450 kHz
• FM-IF gain stage
• Crystal oscillator providing mixer frequencies and references for IF-counter
• FM quadrature demodulator with automatic centre frequency adjustment and THD compensation
• AM-IF-amplifier and demodulator
• I2C-bus transceiver with interface to enable direct data transfer to radio front-end
• IF-count for AM and FM
• Analog-to-digital conversion of level voltage and multi-path information
• Reference frequency generation for PLL synthesizer.
