CS5376A

DS612F4 9

- 37 mW for 4-channel operation at 500 SPS

(9.25 mW/channel).

-40µW 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.
