Analog audio to digital transmitter solution development PCBA
NX8406 is a single-chip CMOS device that transmits and decodes
fiber optic and coaxial digital audio transmission outputs
according to IEC60958, S/PDIF, EIAJ CP1201, or AES3 interface
standards. The ability of NX8406 to perform comprehensive control
through optional control ports in software mode or optional pins in
hardware mode. The channel state data is assembled in a buffer,
making it easy to read and access.
The low jitter clock recovery mechanism generates a very clean
recovery clock from the incoming AES3 stream. Independent operation
allows systems without microcontrollers to use dedicated output pin
operations for channel state data
NX8406 adopts SSOP28 packaging target applications include A/V
transmitters, CD-R, DVD transmitters, multimedia speakers, digital
mixing consoles, special effects processors, set-top boxes,
computers, and car audio systems
