Product Description:
The TDA3540 and TDA3541 are i.f. amplifier and demodulator circuits for color and black and white television receivers, using n-p-n tuners for the TDA3540 and p-n-p tuners for the TDA3541.
The unit incorporates the following functions:
- Gain controlled wide-band amplifier, providing complete i.f. gain
- synchronous demodulator with excellent intermodulation
- white spot inverter
- video preamplifier with noise protection
- a.f.c circuit with a.f.c. on/off switch and a.g.c. circuit with noise gating
- tuner a.g.c. output (n-p-n tuners: TDA3540; p-n-p tuners: TDA3541)
- external video switch which switches off the video output; e.g. for insertion of a VCR playback signal, by either a high or a low level
