Description :

The CXA1145P, CXA1145M 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.


  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
