The CS5376 is a multi-function digital filter utilizing a lowpower signal processing architecture to achieve efficient filtering for up to four ∆− modulators. Used in combination with the CS5371 and CS5372 ∆− modulators, a unique high resolution A/D measurement system results.
Digital filter coefficients for the CS5376 FIR and IIR filters can be programmed for custom applications, or the onchip coefficient set can be used for a simple setup. Filter configuration is initialized through a serial port using a
microcontroller or a configuration EEPROM.
The CS5376 includes a test bit stream generator that produces a 1-bit ∆− modulated output suitable for driving a test DAC. It also includes 12 general purpose I/O pins for local hardware control, a secondary master mode SPI port to communicate with serial peripherals, and an IEEE 1149.1 JTAG test port for boundary scan.
