Philips Semiconductors
Integrated NTSC decoder
and sync processor
Preliminary specification
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
• Low dissipation (320 mW)
• Small amount of peripheral components compared with
competition ICs.
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.
