Description

Design engineers now have an off-the-shelf

precision, dual channel hardware solution for

development of digital FIR filters that can be used

in production subassemblies.

Designers can

generate FIR filter characteristics in a MatLab

TM

V5.3 or V6.0 environment and directly load

standard or custom coefficient sets into the

SPPDM-01 platform via an RS232 interface

located

on

the

users

field

programmable

subassembly or from the SPPDB-01 development

board.

By utilizing the SPPDF-01 hardware with the

enclosed MatLab GUI, generated coefficients are

loaded directly into the removable SPPDM-01

platform

for

insertion

into

finished

EOEM

products.

This

unique

capability

minimizes

product development and manufacturing cycle

times while providing precise unit-to-unit product

matching in a small 2” x 2” footprint that can be

reconfigured or upgraded in the field

.

SPPDM-01 FIR filter platforms operates over a

100 Hz to 20 kHz audio frequency range. Each

channel can be configured to provide up to 9-bits

of filter frequency programmability per channel.

This dual channel DSP design solution contains

anti-alias and reconstruction filters along with

ADC’s and DAC’s offering low noise and distortion

signal processing with THD approaching –100 dB.

Sampling at 48 kHz the fixed point DSP utilizes

32-bit math to achieve 24-bits of precision.

Features/ Benefits:

• Compact 2” x 2” dual channel design

combined with large program memory (256 k

EE-Prom)

and

4-Mbits

of

flash

memory

optimizes DSP processing power in minimal

board space.

• SPPDB-01 development hardware offers rapid

set-up,

programming

and

performance

evaluation,

shortening

the

product

development

cycle

while

insuring

high

precision field programmable installation.

• Field programmability of coefficient sets,

analog I/O and storage for 100’s of application

specific FIR filters provide designers with

unmatched design, implementation and field

upgrade flexibility.
