GENERAL DESCRIPTION
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.
FEATURES
• 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).
