NXP Semiconductors TDA9813T
The TDA9813T is an integrated circuit for vision IF signal processing and sound dual FM demodulation, with single reference QSS-IF in TV and VCR sets. For negative modulation standards only.FEATURES
● 5 V supply voltage● Gain controlled wide band VIF amplifier (AC-coupled)
● True synchronous demodulation with active carrier regeneration (very linear demodulation, good intermodulation figures, reduced harmonics, excellent pulse response)
● Separate video amplifier for sound trap buffering with high video bandwidth
● VIF-AGC detector for gain control, operating as peak sync detector
● Tuner AGC with adjustable takeover point (TOP)
● AFC detector without extra reference circuit
● AC-coupled limiter amplifier for sound intercarrier signal
● Two alignment-free FM-PLL demodulators with high linearity
● SIF input for single reference QSS mode (PLL controlled); SIF-AGC detector for gain controlled SIF amplifier; single reference QSS mixer able to operate in high performance single reference QSS mode
● Stabilizer circuit for ripple rejection and to achieve constant output signals
● ESD protection for all pins. ORDERING INFORMATION PACKAGE TYPE NUMBER NAME TDA9813T SO28
