Philips Semiconductors
VIF-PLL with QSS-IF and
dual FM-PLL demodulator
Product specification
TDA9813T
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.
GENERAL DESCRIPTION
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.
