904 00000214 BA7007 (SECAM Discriminator IC) (16-lead ZIP package) BA7007 SECAM discriminator IC

The BA7007 is a SECAM discriminator suitable for use in video cassette recorders. The BA7007 includes a pre-limiter circuit, detector, slicer-tuning amplifier and comparator. By adding a ceramic filter, and LC circuit for the fHor/2 Oscillation frequency, and a few resistors and capacitors it is possible to construct an extremely sensitive SECAM discriminator using a simple circuit with low space requirements that will lead to lower costs and better performance and reliability.

• Applications
SECAM discriminator for VCRs.

• Features
1)Extremely stable SECAM discrimination even with power supply and burst-signal input level fluctuations.
2)Digital conversion-type integration is used to ensure a large noise margin, and give high sensitivity.
3)Low variation in discriminator sensitivity means that adjustment is not necessary.
4)Few external components required.
5)Large current output capacity. 0.89
