NXP Semiconductors TDA4650
The TDA4650 is a monolitic integrated multistandard colour decoder for PAL, SECAM and NTSC (3.58 and 4.43 MHz) with negative colour difference output signals. The colour-difference output signals are fed to the TDA4660/TDA4661, Switched capacitor delay line.| Part No. | TDA4650 |

FEATURES
Identifies and demodulates PAL, SECAM, NTSC 3.58 and NTSC 4.43 chrominance signals with:● Identification – automatic standard identification by sequential inquiry – secure SECAM identification at 50 Hz only, with PAL priority – four switched outputs for chrominance filter selection and display control – external service switch for oscillator adjustment
● PAL / NTSC demodulation – H (burst) and V blanking – PAL switch (disabled for NTSC) QUICK REFERENCE DATA SYMBOL Vp Ip vi(p-p) Vo(p-p) supply current (pin 13) chrominance input voltage (pin 15) (peak-to-peak value) colour-difference output voltage (pin 1) (peak-to-peak value) colour-difference output voltage (pin 3) (peak-to-peak value) colour-difference output voltage (pin 1) (peak-to-peak value) colour-difference output voltage (pin 3) (peak-to-peak value) ORDERING INFORMATION EXTENDED TYPE NUMBER TDA4650 TDA4650WP Note 1.
