描述 Description

Overview The DSP56651 has been placed on \"NotRecommended for New Designs\" status. This is NOTan End-of-Life Notice.
The RAM-based DSP56651 emulation device is designedto support the rigorous demands of developingapplications for the cellular subscriber market.The high level of on-chip integration in theDSP56651 and its volume production companiondevice DSP56652 minimizes application systemdesign complexity and component count, resultingin very compact implementations.
