Philips Semiconductors
PAL/NTSC encoder
Preliminary specification
TDA8501
FEATURES
Two input stages: R, G, B and (RY), (BY), Y with
multiplexing
Chrominance processing, highly integrated, includes
low frequency filters for the colour difference signals,
and after the modulator a bandpass filter
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 for 75 driving via an external
emitter follower. Internal generation of NTSC setup
Sync separator circuit and pulse shaper, to generate the
required pulses for the processing, clamping, blanking,
FH/2, and burst pulse
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 reset
Internal bandgap reference.
GENERAL DESCRIPTION
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 compatible with the specification of those of the
TDA8505 SECAM-encoder.
