Description
The various versions of the TDA8841 series are I2C-bus controlled single chip TV processors which are intended to be applied in PAL, NTSC, PAL/NTSC and multi-standard television receivers. The N2 version is pin and application compatible with the N1 version, however, a new feature has been added which makes the N2 more attractive. The IF PLL demodulator has been replaced by an alignment-free IF PLL demodulator with internal VCO (no tuned circuit required). The setting of the various frequencies (33.4, 33.9, 38, 38.9, 45,75 and 58.75 MHz) can be made via the I2C-bus.
