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.
