Product Description:
The TCA650 is an integrated synchronous demodulator for both SECAM AND PAL chrominance signals. Switching of the standard is performed internally, controlled by an external applied d.c. signal. In addition to the synchronous demodulator, which delivers color difference signals, the circuit also incorporates the following features:
- A PAL matrix, used for adding the delayed and non-delayed signals to obtain separately the (R-Y) and (B-Y) components of the chrominance signal.
- A PAL switch, which reverses the phase of the (R-Y) component of the chrominance signal on alternating lines.
- A SECAM switch, which performs the separation of the Dr and Db components of the chrominance signal by switching the delayed and non-delayed signals.
- A SECAM limiter.
