DIX4192IPFBG4
集成数字音频接口接收器和发射器 Integrated Digital Audio Interface Receiver and Transmitter
DESCRIPON
The DIX4192 is a highly-integrated CMOS device designed for use in professional and broadcast digital audio systems. The DIX4192 combines a digital audio interface receiver DIR and transmitter DIT, two audio serial ports, and flexible distribution logic for interconnection of the function block data and clocks.
The DIR and DIT are compatible with the AES3, S/PDIF, IEC 60958, and EIAJ CP-1201 interface standards.
The audio serial ports and DIT may be operated at sampling rates up to 216kHz. The DIR lock range includes sampling rates from 20kHz to 216kHz.
