TDA9885 TDA9886 2 I C-bus controlled single and multistandard alignment-free IF-PLL demodulators Rev. 03 16 December 2008 Product data sheet 1. General description The TDA9885 is an alignment-free multistandard (PAL and NTSC) vision and sound IF signal Phase-Locked Loop (PLL) demodulator for negative modulation only and FM processing. The TDA9886 is an alignment-free multistandard (PAL, SECAM and NTSC) vision and sound IF signal PLL demodulator for positive and negative modulation, including sound AM and FM processing. 2.
