ASAHI KASEI www.DataSheet4U.com [AK4126] AK4126 6ch 192kHz / 24-Bit Asynchronous SRC GENERAL DESCRIPTION AK4126 is a 6ch digital sample rate converter (SRC). The input sample rate ranges from 8kHz to 192kHz. The output sample rate is from 8kHz to 192kHz. By using the AK4126, the system can take very simple configuration because the AK4126 has an internal PLL and does not need any master clock Then the AK4126 is suitable for the application interfacing to different sample rates like multi-chan.

ASAHI KASEI www.DataSheet4U.com [AK4126] AK4126 6ch 192kHz / 24-Bit Asynchronous SRC GENERAL DESCRIPTION AK4126 is a 6ch digital sample rate converter (SRC). The input sample rate ranges from 8kHz to 192kHz. The output sample rate is from 8kHz to 192kHz. By using the AK4126, the system can take very simple configuration because the AK4126 has an internal PLL and does not need any master clock Then the AK4126 is suitable for the application interfacing to different sample rates like multi-channel high-end Car Audio, DVD recorder, etc. FEATURES 1.
