Description:
The CXA1145P, CXA1145M, CXA1145 encoder converts an analog RGB signal to a composite video signal. With its built-in circuit various pulses required for an encoder, composite video outputs are obtained just by inputting the composite sync and analog RGB signal.
Features:
1. Single power supply 5V
2. Low power consumption ( 110 mW )
3. Compatible both with NTSC and PAL systems
4. Built-in 75 Ohm driver
5. Built-in oscillator for subcarrier
6. External input of subcarrier is also possible
7. Built-in audio buffer circuit
