SPPPF-01 & 02 Series Dual Channel Analog Inputs & Outputs

SPPPF-01 & 02 Series
Dual Channel
Programmable FIR Filters
Analog Inputs & Outputs
Description
The SPPPF Series of dual channel programmable, FIR
filter platforms, are factory configured, turnkey solutions
that cover the audio bandwidth to +20 kHz. Each
SPPPF-01 provides two independently tuned channels
of on-board analog I/O with 9-bit, (512) tuning while each
SPPPF-02 provides two independently tuned channels
of on-board analog I/O with 8-bit, (256) tuning. SPPPF’s
are easy to use, plug-in modules with no external
components, all packaged in a compact 2” x 2”, low
profile footprint. Each SPPPF contains its own anti-alias
and reconstruction filters along with ADC’s, DAC’s and
analog I/O. The SPPPF’s provide brick wall, linear
phase characteristics with low noise attenuation floors of
-96 dB typical. Sampling at 48 kHz, the fixed point DSP
utilizes 32-bit math to achieve 24-bits of precision for
digital FIR filters with shape factors from 1.03 to 1.50.
SPPPF’s can be provided in several standard or custom
frequency ranges utilizing a broad range of single or
multi-rate brick wall algorithms. An SPPPF-02 (special
LF clock 7.2 kHz) permits ultra low frequency ranges
from 0.1 Hz to 25.6 Hz. All pre-programmed for your
laboratory or field applications.

Features/ Benefits:
• Integrates the best of analog and digital signal
processing to optimize standard and multi-rate FIR
filter performance.
• Each channel can be programmed independently.
• Provides plug-in turnkey solutions with over 500
digitally programmable algorithms per channel.
• All standard and custom solutions combine Brickwall Low-Pass, Band-Pass solutions with linear
phase performance.
• Compact 2” x 2” dual channel design provides
precision performance while minimizing board space
requirements.

Notes:
1. FC1 and FC2 represent the 0dB corner frequencies
2. FS1 and FS2 stopband frequencies.
3. All filters based on 48KHz sampling frequency, -96 dB stopband
attenuation and 0.1 dB passband ripple.
4. Time delays are for the FIR filter only. Additional time delay for
the ADC is approx. 0.2ms and the DAC is 1ms.
