SPPDF-01

FIR Filter Development Suite

for SPPDM-01

Description

The SPPDF-01 is a Development Suite for the dual

channel SPPDM-01 FIR filter platform.

This

provides a user-friendly design environment for

development of Digital FIR filter solutions in the

audio frequency range from 100 Hz to 20 kHz. By

environment and the SPPDF-01 development

software, the suite enables the design engineer to

take advantage of a proven hardware platform with

a built in FIR filter to quickly and easily configure

dual-channel application specific FIR filter solutions.

In a small 2" x 2" footprint, the versatile dual

channel SPPDM-01, the brains of the SPPDF-01,

provides two fully programmed FIR filters.

After

loading the filter coefficient sets via the SPPDB-01

development board, the SPPDM-01 can be easily

removed and inserted directly into a production

subassembly. This capability significantly reduces

the time it takes to produce finished product

solutions. SPPDM-01’s combine 24-bit A/D’s and

D/A’s with a powerful DSP, 4 megabits of flash

memory and 256k bits of EEPROM for applications

requiring low signal-to-noise ratios of > 96 dB,

channel-to-channel phase match of 0.01º, and 9-

bits of tuning per channel.

By utilizing the SPPDF-01 suite of products, design

engineers have all the hardware and software tools

to design, prototype and implement a broad range

of FIR filter solutions in a standard footprint and

form factor.

This product development approach

significantly reduces the time it takes to design an

FIR filter (concept to production).

Features/Benefits:

• Significantly reduces product development time

by

incorporating

design

and

production

capabilities into a single subassembly solution.

• Minimizes design time by offering standard and

custom solutions in a universal footprint and pin-

out.

• Combines small size and precision performance

through the integration of real-time analog and

DSP technology.

• Provides cost effective design flexibility by

allowing engineers to easily revise products

through software upgrades without replacing the

hardware.
