Preliminary specication
Integrated NTSC decoder
and sync processor
TDA8315T
FEATURES
CVBS or Y/C input
Integrated chrominance trap and bandpass filters
(automatically calibrated)
Integrated luminance delay line
Alignment-free NTSC colour decoder
Horizontal PLL with an alignment-free horizontal
oscillator
Vertical count-down circuit

GENERAL DESCRIPTION
The TDA8315T is an alignment-free NTSC decoder/sync
processor. The device can be used for normal television
applications and for Picture-in-Picture (PIP) applications.
The input signal can be either CVBS or Y/C and at the
outputs the following signals are available:
Luminance signal
Colour difference signals (U and V)
Horizontal and vertical synchronization pulses
Back porch clamping pulse (burst-key pulse).
The supply voltage for the IC is 8 V. It is available in a
24-pin SO package.
