Specifications of CDB5374

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

Modulator ∆Σ data is input through the modulator interface.
Test DAC ∆Σ data is generated by the test bit stream generator.
Amplifier, modulator, and test DAC digital pins are controlled by the GPIO port.
The secondary serial port (SPI 2) and boundary scan JTAG port are also on CDB5374.
