CS5376A
DS612F4 9
- 37 mW for 4-channel operation at 500 SPS
(9.25 mW/channel).
- 40
µW standby mode.
• Flexible power supply configurations.
- Separate digital logic core, telemetry I/O,
and modulator I/O power supplies.
- Telemetry I/O and modulator I/O interfaces
operate from 3.3 V or 5 V.
- Digital logic core operates from 3.0 V,
3.3 V or 5 V.
• Small 64-pin TQFP package.
- Total footprint 12 mm x 12 mm plus five
bypass capacitors.
1.4 Configuration Interface
• Configuration from microcontroller or stand-
alone boot EEPROM.
- Microcontroller boot permits reconfigura-
tion during operation.
- EEPROM boot sets a fixed operational con-
figuration.
• Configuration commands written through Seri-
al Peripheral Interface 1. (See Table 1)
- Standardized microcontroller interface us-
ing SPI 1 registers. (See Table 3)
- Commands write digital filter registers, fil-
ter coefficients, and test bit stream data.
- Digital filter registers set hardware config-
uration options.
