CX25840/1/2/3 is a broadcast audio/video decoder family of ICs from Conexant. According to Conexant, its a "... second generation of Audio/Video (A/V) decoders built on the success of the CX23880 family ...". Typically used in combination with other PCI bridge/MPEG encoder chip like CX23415/6/8.

CX2584x chips are fully supported by Linux kernel using the cx25840 driver.

Overview/Features

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
BTSC with DBX No Yes No Yes
