TDA3576B

The TDA3576B is a monolithic integrated color decoder for use in color television receivers. The circuit is optimized for a horizontal and vertical frequency ratio of 625. The feature of TDA2542 are as follows: (1)horizontal sync separator with sliding bias such that the sync pulse is always sliced between top sync level and blanking level; (2)phase detector which compares the  horizontal sync pulse with oscillator voltage; this phase detector is gated; (3)phase detector which compares the horizontal flyback pulse with the oscillator voltage; (4)horizontal oscillator; (5)time constant switching of the first control loop; (6)burst key pulse generator.

The absolute maximum ratings of the TDA3576B are: (1)(1)supply voltage: 13.2 V; (2)total power dissipation: 1200mW; (3)storage temperature range: -55 to +125; (4)operating ambient temperature range: -25 to +65.
