Product Summary
The TDA9808T/V3 is an integrated circuit for single standard (negative modulated) vision IF signal processing and FM demodulation, with single reference QSS-IF in TV and VTR sets.
Parametrics
TDA9808T/V3 absolute maximum ratings: (1)Supply voltage note 1 Tj(max)= 125 °C; TDA9808 (DIP20): 9.9 V; (2)Supply voltage note 1 Tj(max)= 115 °C; TDA9808T (SO20): 5.5 V; (3)Voltage at pins 1, 2, 5, 13, 17, 19 and 20: 0 to VP V; (4)Maximum short-circuit time to ground or VP: 10 s; (5)Tuner AGC output voltage: 0 to 13.2 V; (6)Storage temperature: -25 to +150 °C; (7)Operating ambient temperature: -20 to +70 °C; (8)Electrostatic handling voltage note 2: -300 to +300 V.
Features
TDA9808T/V3 features: (1)5 V supply voltage (9 V supply voltage for TDA9808 (DIP20)only); (2)Applicable for IFs (Intermediate Frequencies)of 38.9 MHz, 45.75 MHz and 58.75 MHz; (3)Gain controlled wide band Video IF (VIF)-amplifier (AC-coupled); (4)True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures, reduced harmonics, excellent pulse response); (5)Robustness for over-modulation better than 105% due to Phase Locked Loop (PLL)-bandwidth control at negative modulated standards; (6)VIF Automatic Gain Control (AGC)detector for gain control, operating as peak sync detector; (7)Tuner AGC with adjustable TakeOver Point (TOP).
