GENERAL DESCRIPTION
The TDA3592A transcoder circuit converts SECAM input signals into true PAL signals, and can be used in combination with all types of PAL decoder.

FEATUREs
• Limiter input for chrominance signal
• SECAM demodulator
• Clamp circuits and de-emphasis for colour difference signals
• Modulator to provide true PAL signals
• 4,43 MHz oscillator
• Sandcastle pulse detector
• Identification circuit for horizontal and vertical SECAM identification
• Can be used with all types of PAL decoder
• Power-saving feature operates when supply voltage falls to (typ.) 5 V:
   SECAM processing shuts down but
   SECAM signal path remains active
