Soundchip Intel

Wer weiss, welche Sampling Rate der Soundchip von Intel 82801DBM hat? Interessiert mich wegen SDR (software defined radio).
Thanks

Hallo,

im Datenblatt (S.242) steht folgendes:

The ICH4 AC ’97 Controller features include:
• Independent PCI functions for audio and modem.
• Independent bus master logic for dual Microphone input, dual PCM Audio input (2-channel
stereo per input), PCM audio output (2-, 4- or 6-channel audio), Modem input, Modem output and S/PDIF output.
• 20-bit sample resolution.
• Multiple sample rates up to 48 kHz.
• 16 GPIOs.
• Single modem line.
• Configure up to three codecs with three AC_SDIN pins.

Und in der Tabelle auf der nächsten Seite:

PCI Audio Function
• Read/write access to audio codec registers 00h–3Ah and vendor registers 5Ah–7Eh.
• 20-bit stereo PCM output, up to 48 kHz (L,R, Center, Sub-woofer, L-rear and R-rear channels on slots 3,4,6,7,8,9,10,11).
• 16-bit stereo PCM input, up to 48 kHz (L,R channels on slots 3,4).
• 16-bit mono mic in w/ or w/o mono mix, up to 48 kHz (L,R channel, slots 3,4) (mono
mix supports mono hardware AEC reference for speakerphone).
• 16-bit mono PCM input, up to 48 kHz from dedicated mic ADC (slot 6)
(supports speech recognition or stereo hardware AEC ref for speakerphone).
• During cold reset, AC_RST# is held low until after POST and software deassertion of
AC_RST# (supports passive PC_BEEP to speaker connection during POST).

Hilft dir das weiter?
