TDA4655 - NXP

TDA4655 Generic multi-standard decoder

TDA4655 The TDA4655 is a monolithic integrated multi-standard colour decoder for PAL, SECAM and NTSC (3.58 and 4.43 MHz) with negative colour difference output signals. It is adapted to the integrated baseband delay line TDA4660/61. MAX. UNIT 8.8 37 296 V mA mW 400 13.2 mV V 624 523 1150 791 662 1460 mV mV mV mV mV mV 1200 1330 CODE SOT234 (1) SO.
