1 FEATURES 2 GENERAL DESCRIPTION
TDA9614H
• All functions controlled by I2C-bus • No adjustments needed by use of auto-calibration circuit • Integrated Bandpass Filters (BPFs) • Low-noise Phase-Locked Loop (PLL) FM (de)modulator • Low-distortion sample-and-hold switching noise suppressor • Integrated HF Low-Pass Filter (LPF) and summator • Integrated audio LPF • 5 stereo inputs (left and right channel): – TUNL and TUNR – CINL and CINR – EXT1L and EXT1R – EXT2L and EXT2R – EXT3L and EXT3R • Additional mono input: Second Audio Program (SAP) • Independent Input/Output (I/O) selections and 2nd line output • Linear audio • DC output for VU meter drive • Direct headphone drive • RF converter output with overload Automatic Gain Control (AGC) • Integrated standby mode for low current consumption • E-E performance (record + playback): – Total Harmonic Distortion (THD): 0.05% (−8 dBV, 1 kHz) – linearity error: 0.1 dB (−88 dBV, 1 kHz) – noise: −93 dBV (20 Hz to 20 kHz). 3 ORDERING INFORMATION
The TDA9614H is an audio processing IC for VHS hi-fi and linear audio, digitally controlled via the I2C-bus. The FM (de)modulator and peak noise reduction functions are highly integrated, resulting in few external components and no external adjustments. In addition special functions for audio mixing, dubbing and descrambling have been implemented.
PACKAGE TYPE NUMBER NAME TDA9614H Note 1. When using IR reflow soldering it is recommended that the Drypack instructions in the “Quality Reference Handbook” (order number 9398 510 63011) are followed. QFP64(1) DESCRIPTION plastic quad flat package; 64 leads (lead length 1.95 mm); body 14 × 20 × 2.8 mm VERSION SOT319-2
