SHARC Processor
ADSP-21469
The ADSP-21469 processor is available with unique audio-
centric peripherals such as the digital applications
interface, DTCP (digital transmission content protection
protocol), serial ports, precision clock generators, S/PDIF
transceiver, asynchronous sample rate converters, input
data port, and more.
