• Internal filter.

GENERAL DESCRIPTION

The TDA9151B 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.
