Description
The CS5378 is a multi-function digital filter utilizing a low-
power signal processing architecture to achieve efficient
filtering for a delta-sigma-type modulator. By combining
the CS5378 with a CS3301/02 differential amplifier, a
CS5371 modulator, and a CS4373 test DAC, a synchro-
nous high-resolution measurement system can be
designed quickly and easily.
Digital filter coefficients for the CS5378 FIR and IIR filters
are included on-chip for a simple setup, or they can be
programmed for custom applications. Selectable digital
filter decimation ratios produce output word rates from
4000 SPS to 1 SPS, resulting in measurement band-
widths ranging from 1600 Hz down to 400 mHz when
using the on-chip coefficient sets.
The CS5378 includes integrated peripherals to simplify
system design: a low-jitter PLL for standard clock or
manchester inputs, offset and gain corrections, a test
DAC bit stream generator, a time break controller, and
eight general-purpose I/O pins.
