All chips of CX2584x family have the same video decoding capabilities.

  • Autodetection and decoding of NTSC (M, J, 4.43), PAL (B, D, G, H, I, M, N, Nc), SECAM (K, L), PAL-60
  • Five-line adaptive comb filter for NTSC and PAL.
  • Two 10 bit ADCs
  • Eight composite inputs
  • Four Y/C inputs
  • VBI data slicing and decoding


Audio decoding capabilities are following:

Capability CX25840 CX25841 CX25842 CX25843
A2, NICAM, AM, FM No No Yes Yes
BTSC, EIA-J Yes Yes No Yes
