TDA8501 Description
TDA8501 The TDA8501 is a highly integrated PAL/NTSC encoder IC which is designed for use in all applications where R, G and B or Y, U and V signals require transformation to PAL or NTSC values.The specification of the input signals are fully patible with the specification of those of the TDA8505 SECAM-encoder.

TDA8501 Key Features
- Two input stages: R, G, B and -(R-Y), -(B-Y), Y with multiplexing
- Chrominance processing, highly integrated, includes low frequency filters for the colour difference signals, and after t
- Fully controlled modulator produces a signal according to the PAL or NTSC standard without adjustments
- A free running oscillator. Can be tuned by crystal or by an external frequency source
- Output stages with separated Y + SYNC and chrominance (Y + C, SVHS), and a CVBS output. Signal amplitudes are correct fo
- Sync separator circuit and pulse shaper, to generate the required pulses for the processing, clamping, blanking, FH/2, a
- H/2 control pin. In PAL mode the internally generated H/2 is connected to this pin and the phase of this signal can be r
- Internal bandgap reference. GENERAL DESCRIPTION
