TDA9151B

Horiz/Vert Deflection IC, PDIP20

GENERAL DESCRIPTION

The is a programmable deflection controller contained in a 20-pin DIP package and constructed using BIMOS technology. This high performance synchronization and DC deflection processor has been especially designed for use in both digital and analog based TV receivers and monitors, and serves horizontal and vertical deflection functions for all TV standards. The TDA9151B uses a line-locked clock at 6.75, 13.5 or 27 MHz, depending on the line frequency and application, and requires only a few external components. The device can be programmed in a self-adaptive mode or in a programmable fixed slope mode. Selection of these modes and a large number of other functions is fully programmable via the I2C-bus.
