Multistandard VIF-PLL with QSS-IF and dual FM-PLL/AM demodulator.

SO28 plastic small outline package, 28 leads, body width 7.5.
GENERAL DESCRIPTION
The TDA9814T is an integrated circuit for multistandard
vision IF signal processing and sound AM and dual FM
demodulation, with single reference QSS-IF in TV and VCR sets
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)
• Robustness for over-modulation better than 105% due
to gated phase detector at L/L accent standard
• VCO frequency switchable between L and L accent
(alignment external) picture carrier frequency
• Separate video amplifier for sound trap buffering with
high video bandwidth
• VIF-AGC detector for gain control, operating as peak
sync detector for B/G and peak white detector for L
(optional external AGC); signal controlled reaction time
for L
• 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

AM demodulator without extra reference circuit
• Stabilizer circuit for ripple rejection and to achieve
constant output signals
• ESD protection for all pins

PLEASE NOTE!

These parts came to us as part of a lot of surplus stock from a large Milspec type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’, they are however pristine, the photographs are representative of their excellent condition, being of one of our actual stock, and, as with all our products they come with a full guarantee. 

If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
