AD14160

The AD14160/AD14160L Quad-SHARC Ceramic Ball Grid Array (CBGA) puts the power of the first generation AD14060 (CQFP) DSP multiprocessor into a very high density ball grid array package; now with additional link and serial I/O pinned out, beyond that from the CQFP package. The core of the multiprocessor is the ADSP-21060 DSP microcomputer. The AD14x60 modules have the highest performance-density and lowest cost- performance ratios of any in their class. They are ideal for applications requiring higher levels of performance and/or functionality per unit area.

The AD14160/AD14160L takes advantage of the built-in multiprocessing features of the ADSP-21060 to achieve 480 peak MFLOPS with a single chip type, in a single package. The onchip SRAM of the DSPs provides 16 Mbits of on-module shared SRAM. The complete shared bus (48 data, 32 address) is also brought off-module for interfacing with expansion memory or other peripherals.

The ADSP-21060 link ports are interconnected to provide direct communication among the four SHARCs as well as high
speed off-module access. Internally, links connect the SHARC in a ring. Externally, each SHARC has a total of 160 Mbytes/s link port bandwidth.

Multiprocessor performance is enhanced with embedded power and ground planes, matched impedance interconnect, and optimized signal routing lengths and separation. The fully tested and ready-to-insert multiprocessor also significantly reduces board space.
