Overview
INTEGRATED CIRCUITS DATA SHEET TEA6823T; TEA6825T In Car Entertainment (ICE) car radio Preliminary specification File under Integrated Circuits, IC01 1998 Mar 24 Philips Semiconductors Preliminary specification In Car Entertainment (ICE) car radio FEATURES General • 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-count and stereo decoder • FM quadrature demodulator with automatic centre frequency adjustment and THD compensation • Level, multi-path and noise detectors • Soft mute • Stereo noise cancelling and variable de-emphasis • PLL stereo decoder • Noise blanker • 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 • Reference frequency generation for PLL synthesizer.
ORDERING INFORMATION PACKAGE TYPE NUMBER NAME TEA6823T TEA6825T VSO56 VSO56 DESCRIPTION plastic very small outline package; 56 leads Stereo decoder TEA6823T; TEA6825T • Adjustment-free PLL VCO • Pilot depending mono/stereo switching • Analog control of mono/stereo blend • Adjacent channel noise suppression (114 kHz) • Pilot cancelled • Analog control of de-emphasis • Integrated low-pass filters for 190 kHz adjacent channel interferences and signal delay for interference absorption circuit.
GENERAL DESCRIPTION The TEA6823T together with the TEA6811T and the TEA6825T together with the TEA6810T form an AM/FM electronic tuned car radio in a double conversion receiver concept.
