DICE JR is a monolithic CMOS ASIC capable of receiving and transmitting up to 64 channels of audio data in accordance with the IEEE 1394 standard. DICE JR also functions as a cross bridge switch between any combination of AES3, ADAT®, ADC and DAC ports. The DICE JR technology simplifies the interface to IEEE 1394 and other popular digital audio formats, while it maximizes the clocking accuracy of audio samples. Unique to the DICE JR is patented JETTM PLL technology and a 18x16 hardware mixer with hardware metering support. With its high integration, JETTM PLL technology, and support of IEEE 1394b DICE JR gives FireWire the versatility necessary for professional and consumer audio markets. Now low cost CAT-5 cable has 100 meter support at the full data rates of all popular digital audio formats. DICE JR’s broadband streaming engine handles all aspects of moving data without placing realtime load on the host processor (ARMTM). The full SDK supports Hardware Abstraction Layer (HAL) libraries and IEEE 1394 stacks with support for OGT, AVC (Class Compliant) and TCP/IP . | |
