Page 4: Overview
Overview Danville Signal's dspblok™ family of products delivers the power of digital signal processing in a small 60mm x 60mm form factor. Connections are brought out to standard 2mm dual row headers. The dspblok reduces development costs, risk and time. Danville’s dspblok DSP function modules are often incorporated directly into larger custom embedded systems. -
Page 5: Intended Audience
The dspblok 21469 requires an understanding of the Analog Devices’ ADSP-21469 and the associated tools used for development. If the dspblok 21469 is going to be integrated into a larger hardware design, then it is also assumed that the user is familiar with basic hardware design. In most cases, systems integrators, DSP programmers and software engineers can create DSP embedded systems using our embedded dspblok systems (or dspstak family) without the need for additional hardware design and manufacturing. - Page 6 21469 with an external ADI ICE : Start your development with a dspblok 21469 module. In this case, you will want to connect to the dspblok 21469via an external Analog Devices emulator. Analog Devices offers two versions the USB- ICE and the HPUSB-ICE.

1.1V to the ADSP-21469. DO NOT use a higher voltage supply for the core supply input (JH4-Vdd). A single 3.3V supply is all that is required to power the dspblok 21469, but in some cases, a 5V supply may be more convenient. The DSP I/O and Memory supply must be 3.3V. - Page 10 room temperature. The Analog Devices’ ADSP-21467/ADSP-21469 SHARC Processor Data Sheet has an excellent section on estimating power consumption of the DSP. Please note that the measurements do not take into account the increase static current as temperature rises. Typical Power Consumption at Room Temperature Core Continuous Mixed...

MS0#, which is not available because its address is assigned to DDR2_CS#. The dspblok 21469 uses a 1Gb (64M x 16) DDR2 DRAM. DDR2 memory is much faster and typically much larger than older SDRAM. PC board layout is non trivial. The dedicated DDR2 interface of the ADSP-21469 has been carefully laid out with respect to trace length, signal integrity, and bus isolation so that the DDR2 operates reliably at maximum speed. -

JTAG chaining applications. Danville has an ADI JTAG adapter available (P/N A.08153). The dspblok 21469+ICE omits JH1 since the debugger is on-board. If you want to use an external emulator or the Danville dspFlash Blackfin & SHARC Programmer, you may remove the ADI Debugger and use the JTAG connection provided below the debugger. -
Page 16: Jh5, Jh7 - Data Bus
This is also why there are unused pins on JH5. If you are adapting a dspblok 21369zx design to support the dspblok 21469, you should verify that these changes will not impact your design. In most cases, this will not be an issue. -

Analog Devices' Debug Agent 60.00 [2.36] The dspblok 21469+ICE board has identical mounting holes and mating connections as the production dspblok 21469. Two additional mounting holes are provided for support as shown. The debugger portion of the dspblok 21469+ICE is USB bus powered. -
Page 19: Product Warranty
If Danville Signal Processing receives notice of such defects during the warranty period, Danville Signal Processing shall, at its option, either repair or replace software media or firmware, which do not execute their programming instructions due to such defects. -
Page 20: Rohs & Weee Compliance
Military, medical and some other products are also exempt. We suggest that you make an appropriate assessment concerning your products. The dspblok 21469 is RoHS compliant. The dspblok 21469 is a subcomponent of a larger system; therefore it is not subject to the WEEE directive EU Directive 2002/96/EC. dspblok™ 21469 User Manual...
