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
Analog video inputs
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
Analog audio inputs
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 |
