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. By taking advantage of pretested signal processing modules, pc board layouts become simpler and
projects are completed quickly and cost effectively. Danville’s dspblok DSP Engines are largely pin
compatible. This allows your application to take advantages of new processor technology and extended
features in the future.
You can also create small standalone embedded applications by combining a dspblok DSP function module
with other dspblok modules. Embedded dspblok systems can be created by using a dspblok power supply
such as our dspblok ps-uart, and an I/O module, such as one of our dspblok ad96k family of audio data
converter boards. Each board is stacked via 2mm headers to create a low profile configuration where space is
at a premium. We also have combination power supply- I/O boards such as our dspblok a9238/48 high-
speed ADC boards for SDR applications.
Danville dspblok DSP Engines are the driving force behind many of Danville’s standalone products such as
our dspstak
, dsprak
, dspMusik
and dspInstrument
product lines.
dspblok™ Development Boards
All dspblok production modules have a companion developer’s version, which includes an Analog Devices’
EZ-KIT style debugger. These boards are physically larger (60mm x 115mm) to accommodate the debugger
but have a matching footprint to our production modules (60mm x 60mm). Once you have developed and
debugged your software, you can replace the debugger module (ICE version) with a lower cost, smaller
production module.
The dspblok “with ICE” versions include the free Visual DSP++ KIT license and are supported by the FULL
version. Depending on the complexity of your application, you may be able to create and support your
application without ever needing to purchase additional development tools. You can also use Analog
Devices’ CrossCore Embedded Studio.
dspblok™ 21469
The dspblok™ 21469 is a highly integrated DSP module that incorporates an Analog Devices’ ADSP-21469
SHARC DSP operating at 450 MHz with flash, EEProm and DDR2 SDRAM memory. An onboard switching
power supply supports the core voltage requirements of the DSP so that only 3.3V is required to power the
dspblok. The ADSP-21469 peripherals include SPORTS (8), SPI(2), TWI (I2C), UART, timers, PWMs, JTAG,
an 8 bit wide data bus and LINK ports(2). All of these peripherals are available via 2mm headers on the
dspblok.
